  • I’m with you on that last bit. The problem that we have with cars is the way that almost everybody is forced to use one for every trip to go anywhere, or at least forced to own a car for many trips. We can’t sustain that economically (I believe that car ownership is a financial burden for around 1/4 of Americans, and our infrastructure rates at D+ nationally), ecologically (climate change is only part of it, the direct ecological destruction is also enormous), and even psychologically (the loneliness epidemic). I’d be over-the-moon if everybody had a choice of a convenient alternative to a single-passenger car for any trip that they wanted to do, with cars as the luxury alternative.





  • Those are fine examples to prove my point. Even the low-end, just-get-around cars have climate controls, entertainment systems, and plush seating. They’re about more than utility, just getting from one place to another. For the CRV, the web site for it really wants to sell the image of adventure, like driving one means you’re ready to head out on road trips, and listen to the Bose sound system while doing so. The base model is also 190hp. The Sentra is 149hp, and over $20,000 base price. Compare that to the Ford Model T, at around $6,000 (inflation adjusted). That was 20hp. Twenty horsepower, no air conditioning, no power steering, no Apple CarPlay, and people drove them across the continent.

    Anyway, I just got home from some errands, and while out, I saw a guy driving a big, shiny, white Ford Model F truck, and wearing a cowboy hat. There are no cattle ranches in Wisconsin. Also, it’s January and he wasn’t wearing a coat; he doesn’t plan to go outside. The car one drives is totally a fashion statement. Driving a low-end car conveys a message about you, just like wearing off-the-rack versus bespoke clothes. Even Warren Buffett’s econobox is a statement.

    And that’s leaving aside the assumption that getting from place to place has to involve a car.




  • As an American, I’m gonna barge in with my loud opinion, 'cuz that’s what we do. Here’s something which people living elsewhere might not know that Americans aren’t ready to hear:

    Automobiles are luxury toys and fashion accessories, and we shouldn’t base our entire lives on them. No, the car industry didn’t make our economy strong; it took off after we already had a lot of extra wealth to burn after becoming a world economic powerhouse. We can’t afford to keep wasting all that wealth on them as the world starts to burn, and half of our citizens sink into poverty.




  • Stereo vision isn’t very different. Human pupils are only 5-6cm apart, so the effect is only useful for objects less than 20-30 meters away, maybe 50 tops. It only works in the center of our visual field, not in the periphery (that only one eye can see). And then, only on the horizontal, left-right axis. Beyond that, we do depth perception the same way: mostly through experience, parallax, context clues, motion prediction, atmospheric distortion, and the like. It doesn’t change the imagery at all, it’s the same scene if I close one eye. I’m guessing that most people who woke up in a familiar environment (e.g. their bedroom) without stereo vision would take a while to notice.
