Robocars As the Best Way Geeks Can Save the Planet

Brad Templeton writes "I (whom you may know as EFF Chairman, founder of early dot-com Clari.Net and rec.humor.funny) have just released a new series of futurist essays on the amazing future of robot cars, coming to us thanks to the DARPA Grand Challenges. The computer driver is just the beginning — the essays detail how robocars can enable the cheap electric car, save millions of lives and trillions of dollars, and are the most compelling thing computer geeks can work on to save the planet. Because robocars can refuel, park and deliver themselves, and not simply be chauffeurs, they end up changing not just cars but cities, industries, energy, and — by removing dependence on foreign oil — even wars. I, for one, welcome our new robot overlords." (More below.) Templeton continues: "The key realization is that while the safety and timesavings that come from having computers as chauffeurs is very important and can save a million lives every year, a number of interesting consequences come from the ability of robocars to drive themselves while vacant. This allows them to deliver themselves to us on demand, to park themselves and to refuel/recharge themselves. On-demand delivery makes car sharing pleasant and allows the use of "the right vehicle for the trip" on most trips. Self-refueling means the people using cars no longer need care about range or how common fueling stations are, enabling all sorts of novel energy systems with minimal "chicken and egg" problems. Because passengers don't care about the range of their taxis, battery weight and cost are no longer issues in electric cars and scooters."

    I scoffed a bit when I RTFS, but the essays are really good and make an excellent case. I read them looking for gaping holes to point out, but really didn't find any major unaddressed concerns. I have to say RTFA is highly recommended. Read it, you won't be sorry.

      I hope I don't gloss over this (read the roadblocks section.) There are many technical and political problems to solve.

      As for energy, the goal is to use far less energy than we use today (whether it's cheap or clean is nice but orthogonal) and it's far from limitless.

      The AI is not so powerful. Most animals can navigate in traffic of their own kind, even insects. But no, it's no tiny project -- but it's a tractable large project.

      You don't need to solve traveling salesman! In fact, I believe centralized control is a bad idea. You can solve traveling salesman over small problem sets, it's only trying to solve it for large numbers that's explosively NP.
      You just have to do better than we do today.

      You'll die first. People have been proposing such a system for aircraft for a very long time due to the dangers inherent in letting people operate such missiles. Even after 9/11, no such system has been implemented. Sometimes I think Asimov managed to scare everyone away from AI just a little too well. Skynet didn't help things either.

      Why do we even need AI for this? There's a wonderful invention called the railroad that has moved people and goods for nearly 2 centuries. Railroads take less energy. No steering required, all that is needed is throttle control.

      Whether or not rails are used, AI can be dispensed with by putting dumb signal readers in the cars, and having senders all along the roads. I recall reading of just such a project some years ago. We have signs all over the place advising drivers how fast to take corners and other such notices. Shouldn't be too difficult to make that all automatic. The vehicle will do only 3 things: don't collide with other vehicles, move at the speeds the road tells it to, and enter and exit the road system when the passengers wish.

    The reason cars don't drive themselves is not a problem of technology, but of liability. Now, if there is an accident the driver is blamed. Carmakers are unwilling to take on that liability and themselves be blamed for accidents.

    Go deeper into the article about the end of transit. Buses are actually quite inefficient, because while loaded at rush hour, on average they carry few passengers. In the USA, city buses use more fuel per passenger-mile than cars do -- on average. And none of the other forms are a great deal better, though some do beat cars. Lightweight electric vehicles are 10 times more efficient than buses. It's one of the key realizations about transit in the article.

    I give a talk on the consequences of Moore's Law to a freshman class every year, and one of my topics is autonomous vehicles. This web site does a great job of summarizing the future of personal transportation. A few other points I discuss with the class:

    (1) Mass transit as we think of it will largely vanish within 20 years. Cities will find it far easier to maintain fleets of robocars, and dispatch them right to the doors of residents, rather than maintain traditional subway and bus lines. The "last half-mile" problem of getting from the door of your home to the door of your destination will be solved.

    (2) The authors discuss "sleeper cars", but they don't really consider all the ramifications. A huge chunk of overnight business travel (everything within a few hundred miles) will be taken over by robocars. People will go to bed in the sleeper car, open the door the next day, and find themselves at their destination. Consequently, hotels and motels will offer short-term rooms (for one or two hours) so that people can shower and dress on the road. A significant portion of the U.S. population will literally become nomadic, sleeping in robotic RVs every night, and waking up to a new destination every morning.

    (3) Once robocars are widely accepted, human drivers will be forced off the roads very quickly. How? By 100% enforcement of all traffic laws with high-tech imaging (also thanks to Moore's Law). A human will be unable to conform to the ultra-rigid driving laws that robocars will handle with ease.

    As I say to my students: "You are the last generation that will need to learn to drive. To your children, it will be an option. To your grandchildren, knowing how to drive a car will be as quaint a concept as knowing how to saddle and ride a horse."

    Prevention is always better than cure. Better to go back to building cities so that they can meet their original purpose of putting daily needs within walking distance. Better to fix the leak rather than put a bigger or more sophisticated bucket under it.

    While there are certainly advantages to living in geographically self-contained units, there are also massive benefits to centralizing industries.

    Yes, the "slow foods" movement will tell us, accurately, that shipping our produce from hundreds of miles away causes an incredible amount of waste in fuel.

    But consider the alternative - a small farm for every nine city blocks. Suddenly, instead of having a system where one farmer can produce food for a thousand, you have a system where one farmer produces food for, say, fifty. Which means you have to have 20 times more farmers. Which means there are fewer people to provide other services. The same goes for commerce: five corner stores might be more convenient than one larger, more centralized 7-11 - but now you have five times as many people working in low-end retail.

    It's centralization of the more menial services that allow so many of us to have jobs in less immediately-necessary services - like programming or science. And almost-completely-unnecessary services, like video game design and filmmaking? Forget about it.
