The Pros and Cons of Driverless Cars

Picture this: You’ve had a long arduous day at work, you’re stressed, not mention possibly more tired than you ever have been in your entire life. You’ve finally left the office, but there’s a problem – you still have to drive home.

 

Road safety campaigners will tell you just how dangerous it is to drive when you’re tired. Reactions are slow, you daydream, you will get impatient so you might take unnecessary risks. The advice is simple – if you’re tired don’t drive.

 

There is a solution: driverless cars. In 2010 Google fitted seven Toyota Priuses with radars, sensors, maps, laser rangefinders and a whole load of other technical wizardry, which meant these cars could drive all by themselves without human input.

 

Pretty impressive I think you’ll agree, and the project is getting closer to one day being rolled out globally. This is all great, but what are the pros and cons of driverless cars?

 


 

Pros

The fleet of self-driving Google cars have so far clocked-up more than 300,000 miles without an accident, whereas if there’s a human at the wheel the average is 165,000 miles.

 

You won’t need to worry about driver fatigue. Whether it’s as in the scenario above or if you’re on a long journey and you feel yourself getting tired you can switch to “driverless mode” and continue with your trip – although it might look strange to other motorists to see you snoring away in your seat. The gift of time!

 

You’ll often see people commuting to work on the train or the bus flicking through paperwork or preparing for a presentation. Your driverless car will give you that time where you’ll have nothing better to do plus there’s the added advantage of peace and quiet.

 

Cons

There’s no substitute for experience. They say that you only start to learn to drive properly after you have passed your driving test.

 

You also need to be confident in your own ability, which only comes with years of practice. Like any other skill, your driving ability will diminish the longer you go without using it, so if you have a driverless car you may be inclined never to take control.

 

When driverless cars become more commonplace it will be interesting to see if hours logged in “driverless mode” will be a consideration when you’re looking for a car insurance quote.

 

When you’re looking for a quote, the more experienced you are the better deal you can get, for example compared to a teenager, who has just passed his or her test, compared to someone with several years of experience. It will be interesting to see how the technology develops in the years to come.

TECHNOLOGICAL ESSENTIALS FOR

‘AUTO-PILOT’ CARS

 

LIDAR: Lidar (also written LIDAR, LiDAR or LADAR) is a remote sensing technology that measures distance by illuminating a target with a laser and analyzing the reflected light. Although thought by some to be an acronym of Light Detection And Ranging,[1] the term lidar was actually created as a portmanteau of “light” and “radar“.[2][3] Lidar is popularly used as a technology to make high-resolution maps, with applications in geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, remote sensing, atmospheric physics,[4] airborne laser swath mapping (ALSM), laser altimetry, and contour mapping.

How do self-driving cars work?

Self-driving cars in a nutshell

A self-driving car is capable of sensing its environment and navigating without human input. To accomplish this task, each vehicle is usually outfitted with a GPS unit, an inertial navigation system, and a range of sensors including laser rangefinders, radar, and video.  The vehicle uses positional information from the GPS and inertial navigation system to localize itself and sensor data to refine its position estimate as well as to build a three-dimensional image of its environment.

 

Data from each sensor is filtered to remove noise and often fused with other data sources to augment the original image. How the vehicle subsequently uses this data to make navigation decisions is determined by its control system.

http://robohub.org/tag/robohub-focus-on-autonomous-driving/

 

The majority of self-driving vehicle control systems implement a deliberative architecture, meaning that they are capable of making intelligent decisions by 1) maintaining an internal map of their world and 2) using that map to find an optimal path to their destination that avoids obstacles (e.g. road structures, pedestrians and other vehicles) from a set of possible paths. Once the vehicle determines the best path to take, the decision is dissected into commands, which are fed to the vehicle’s actuators. These actuators control the vehicle’s steering, braking and throttle.

 

This process of localization, mapping, obstacle avoidance and path planning is repeated multiple times each second on powerful on-board processors until the vehicle reaches its destination.


The next section focuses on the technical components of each process: mapping and localization, obstacle avoidance and path planning. Although car manufacturers use different sensor suites and algorithms depending on their unique cost and operational constraints, the processes across vehicles are similar. The descriptions below most closely mirror their implementation in state-of-the-art self-driving military vehicles.

 

Breaking Down the Technicals

Mapping and Localization

 

Prior to making any navigation decisions, the vehicle must first build a map of its environment and precisely localize itself within that map. The most frequently used sensors for map building are laser rangefinders and cameras. A laser rangefinder scans the environment using swaths of laser beams and calculates the distance to nearby objects by measuring the time it takes for each laser beam to travel to the object and back. Where video from camera is ideal for extracting scene color, an advantage of laser rangefinders is that depth information is readily available to the vehicle for building a three-dimensional map. Because laser beams diverge as they travel through space, it is difficult to obtain accurate distance readings greater than 100m away using most state-of-the-art laser rangefinders, which limits the amount of reliable data that can be captured in the map. The vehicle filters and discretizes data collected from each sensor and often aggregates the information to create a comprehensive map, which can then be used for path planning.

 

For the vehicle to know where it is in relation to other objects in the map, it must use its GPS, inertial navigation unit, and sensors to precisely localize itself. GPS estimates can be off by many meters due to signal delays caused by changes in the atmosphere and reflections off of buildings and surrounding terrain, and inertial navigation units accumulate position errors overtime. Therefore localization algorithms will often incorporate map or sensor data previously collected from the same location to reduce uncertainty. As the vehicle moves, new positional information and sensor data are used to update the vehicle’s internal map.

 

Obstacle Avoidance

A vehicle’s internal map includes the current and predicted location of all static (e.g. buildings, traffic lights, stop signs) and moving (e.g. other vehicles and pedestrians) obstacles in its vicinity. Obstacles are categorized depending on how well they match up with a library of pre-determined shape and motion descriptors. The vehicle uses a probabilistic model to track the predicted future path of moving objects based on its shape and prior trajectory. For example, if a two-wheeled object is traveling at 40 mph versus 10 mph, it is most likely a motorcycle and not a bicycle and will get categorized as such by the vehicle. This process allows the vehicle to make more intelligent decisions when approaching crosswalks or busy intersections. The previous, current and predicted future locations of all obstacles in the vehicle’s vicinity are incorporated into its internal map, which the vehicle then uses to plan its path.

 

Path Planning

The goal of path planning is to use the information captured in the vehicle’s map to safely direct the vehicle to its destination while avoiding obstacles and following the rules of the road. Although manufacturers’ planning algorithms will be different based on their navigation objectives and sensors used, the following describes a general path-planning algorithm, which has been used, on military ground vehicles.

 

This algorithm determines a rough long-range plan for the vehicle to follow while continuously refining a short-range plan (e.g. change lanes, drive forward 10m, turn right). It starts from a set of short-range paths that the vehicle would be dynamically capable of completing given its speed, direction and angular position, and removes all those that would either cross an obstacle or come too close to the predicted path of a moving one.  For example, a vehicle traveling at 50 mph would not be able to safely complete a right turn 5 meters ahead, therefore that path would be eliminated from the feasible set.  Remaining paths are evaluated based on safety, speed, and any time requirements. Once the best path has been identified, a set of throttle, brake and steering commands, are passed on to the vehicle’s on-board processors and actuators. Altogether, this process takes on average 50ms, although it can be longer or shorter depending on the amount of collected data, available processing power, and complexity of the path-planning algorithm.

 

The process of localization, mapping, obstacle detection, and path planning is repeated until the vehicle reaches its destination.

 

The Road Ahead

Car manufacturers have made significant advances in the past decade towards making self-driving cars a reality; however, there still remain a number of technological barriers that manufacturers must overcome before self-driving vehicles are safe enough for road use. GPS can be unreliable, computer vision systems have limitations to understanding road scenes, and variable weather conditions can adversely affect the ability of on-board processors to adequately identify or track moving objects. Self-driving vehicles have also yet to demonstrate the same capability as human drivers in understanding and navigating unstructured environments such as construction zones and accident areas.

-

These barriers though are not insurmountable. The amount of road and traffic data available to these vehicles is increasing, newer range sensors are capturing more data, and the algorithms for interpreting road scenes are evolving. The transition from human-operated vehicles to fully self-driving cars will be gradual, with vehicles at first performing only a subset of driving tasks such as parking and driving in stop-and-go traffic autonomously. As the technology improves, more driving tasks can be reliably outsourced to the vehicle.

 

The technology for self-driving cars is not quite ready, but I am looking forward to the self-driving cars of Minority Report becoming a reality.

Tabacco: Developing a Car, which could run with WATER as fuel (impossible dream of course), would be mahvelous because it would SCREW Capitalist Energy Exploiters like ExxonMobil and BP! But then they would probably just raise the Price of Water and call it Automotive H3O or something!

 

But if Driverless Car Technology drives down Annual Motor Deaths > 40,000 per year > 30,000 per year > 20,000 per year > 10,000 per year > 0 per year, all other considerations aside, this would be the biggest and greatest invention of the 21st century. And only the cessation of War, Genocide and Poverty caused by Unfettered Capitalism could surpass it!

 

Convenience, Job Loss or Gain, Profit & Loss, Potential Transportation Availability for Physical Handicapped are all Pluses for the Driverless Car, but none of these individually or collectively is the most important Potential Gain!

 

Nothing ever created by Mankind has EVER been PERFECT! But driving Annual Auto Deaths downward toward 0 would be very close! Watch those Numbers! Watch those Numbers! This is the PRIMARY BENEFIT POSSIBLE for the Driverless Car!


Tabacco: I consider myself both a funnel and a filter. I funnel information, not readily available on the Mass Media, which is ignored and/or suppressed.

When you read Tabacco, if you don’t learn something NEW, I’ve wasted your time.

 

 

If Tabacco is talking about a subject that nobody else is discussing, it means that subject is more, not less important, and the Powers-That-Be are deliberately avoiding that Issue. To presume otherwise completely defeats my purpose in blogging.

    DON’T DO IT UNLESS AND UNTIL!

    Unless and Until you hear the words ‘Electric Car’ or at the very lest that half-stepper ‘Hybrid’, DON’T DO IT! DON’T BUY A DRIVERLESS CAR!

    WHY NOT? 1- Gasoline is on its way out of here! Natural Gas and Coal, which will succeed Petroleum, will follow soon after. The Automakers know this, but they want to do what? SELL MORE CARS!

    So long as folks like you are willing to fork over small fortunes for Gasoline, Automakers will continue to peddle GAS GUZZLERS!

    Only when a Gallon approaches $10 or $20 will they truly push Electric Driverless Cars! SO DON’T WASTE YOUR MONEY! One day Gas Guzzlers will dot the entire American landscape, abandoned as worthless. When that day comes, nobody will give you a dime for one except to salvage the metal – if any!

    A Word to the Wise is Sufficient!

    I STILL DON’T KNOW:

    How do ‘Driverless Cars’ feel about POTHOLES? Will they AVOID POTHOLES or SWERVE TO HIT THEM DEAD ON? I wonder if those ‘Driverless’ Geniuses have even considered that Variable! Geniuses and Capitalists often miss the Forest for the Trees!

    POTHOLES, Google, POTHOLES!
