Autonomous Cars Could Be Worse For Carbon Emissions

HughPickens.com writes: David Roberts writes at VOX that it stands to reason that vehicle automation could save energy and reduce emissions in some ways. Cars will be able to chain together more aerodynamically, drive at more consistent speeds, and perhaps serve as shared vehicles in lieu of individual vehicle ownership. But it also stands to reason that automation could increase energy use and emissions in some ways. If driving is easier and more pleasant, people will do it more. Automation will open up car travel to populations (the young, the elderly, the visually or otherwise impaired) who did not previously have access. Self-driving cars could increase the overall amount of vehicle miles traveled. (Read more, below.) Hugh Pickens continues: A new study: "Help or hindrance? The travel, energy and carbon impacts of highly automated vehicles," suggests that the big swing factor is travel cost reduction — in other words, how cheap and easy driving gets. If that stays at the low end, then the effects of self-driving cars on energy use are almost certain to be a substantial net positive. However if it reaches the high end, a 60 percent boost in energy consumption for transportation, all the energy-saving benefits could be wiped out, for a net increase in energy and emissions. "This leads to somewhat surprising policy implications It may be that the socially optimal outcome, at least for now, is partial, not full, automation. That way the energy and emissions benefits of smarter driving practices can be fully captured, without allowing drivers to tune entirely out — without making it too easy," concludes Roberts. "Perhaps when we get farther down the road (ahem) — when more vehicles are electrified, when car sharing is more firmly established, when the benefits of automation have proven out — we can move to full automation without the risk of carbon blowback."

    How much "carbon emissions" will be caused by all the funerals, ambulance trips, etc. this entails?

    Not nearly as much as those 1 million people would have created had they lived out the rest of their natural lives. The fact they were killed prevents enormous quantities of greenhouse gas emissions going forward.

    Electric cars will take over.

    Once upon a time, CRT monitors were everywhere. LCDs were desirable but they were newer than CRTs, thus more expensive to make. But as the cost of manufacturing LCDs came down close to CRTs, they took over. All other things being equal, LCDs were more desirable than CRTs *AND* they were LESS expensive to ship. Ergo, they won.

    Now, gas cars were everywhere. Electric cars are more desirable (in general) but they are newer than gas cars, thus more expensive to make. But as the cost of manufacturing electric cars comes down, they'll take over. All other things being equal, electric cars will be more desirable than gas cars (cheaper to "fill", quieter, etc.) *AND* they'll eventually be LESS expensive to make since they are much less complicated than gas cars. Ergo, they'll win.

    LCDs had some other obstacles to overcome, eg. image quality, but eventually, that got worked out. Electric cars have some obstacles to overcome, eg. range and charge time, but that will get worked out. As of this minute, a Tesla Model S is just about perfect for most families, other than that it currently costs $90k. But remember when 15-20" LCD monitors were $2,000?

    The same thing happened with the advent of computers. When computers came out, they made a lot of human jobs obsolete. The glut of unemployment drove down wages, and nobody but the very rich could afford the computers. To this very day, only the top 1% own computers.

    Most successful people do because most successful people are. The ethical trick is to keep to making the best of bad situations caused by others, rather than causing them yourself.
