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."

    I'm more worried about how much NO/NO2 they are putting out than CO2. Carbon dioxide is mostly harmless, but nitrous is dangerous.

    Agreed. Nitrous oxide is no laughing matter.

    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.

    My plan is to just set the car to roam around while i'm not using it, so at least one of us is having a good time.

    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?

      "ICE engines are amazing now with computer control. I have no desire to stop shifting mine. :)"

      I've been driving cars for 35 years, mostly manuals, mostly petrol although I did own a 6 speed diesel once. I've taken petrol engines completely apart and rebuilt them. You could say I'm a bit of a petrol head. And yet, last year I took a test drive in a Nissan Leaf which is frankly a pretty cheap little car. That thing runs like it is a Rolls Royce. Incredibly smooth, with a really sudden and direct throttle with no lag whatsoever. Sure, the range isn't great but It took a look at my current petrol car and I only do mostly short journeys well within the range of the Leaf and if I need to go further I can always rent. I was convinced and I've bought a brand new Leaf. Petrol cars and the ICE are dinosaurs. They're slow, unresponsive and wasteful. Even the whole range and fuel thing is a non-issue for the vast majority of users because, while most people think they need to be able to drive 300 miles all the time, they don't. I fill my car up once a month and I do around 300 miles a month in it. That means each week I do about the range of the Leaf and the Leaf is always fully charged and ready to go. Plus, I have rooftop solar so the usual argument that I'm just moving the pollution to the power station doesn't hold because my car is going to use 100% renewable fuel. I've switched power companies to a carbon zero supplier that buys my excess power and also has a good plan for people with solar and EVs. This is the future. The ICE has had its day. It was fun, but oily and dirty and I'm happy to move on.

    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.

    Don't let this click bait headline fool you.

    Truth. Vox dot com is a garbage media source. They specialize in these "hot takes" that always end up to be shallow Freakonomics horseshit. "Gee, some studies suggest smoking may actually be good for you!" or "Why do so many successful people drink water?"

    I'm not saying it's because Vox is made up of a bunch of 20-something journo students who couldn't find jobs anywhere else, or that it's because Ezra Klein was one of the founders. It might be something else.

    Vox likes to set up their stories as "explainer cardstacks" (yes, this is a term of art). It means basically great big graphics with no indication of data sources and video. And they wrap it all up in ugly typography and web design that makes it one of the least pleasurable spots on the Internet. Don't believe me? See for yourself. But wait: it's also one of those sites that if you happen to use adblock or a script blocker, just turns to a long, ugly list of links, looking like something circa 1993.

    I hate Vox. It's Forbes, except run by a bunch of 20-somethings with associates degrees in art & design.
