If you dig even further, you will find things like 'unhappy people consume more as they try to buy their way out of misery'. Now of course you don't directly sell unhappiness, but you can sell goods of which the consumption benefits the individual that consumes it, but deteriorates the world a little bit for everyone as a result. A car is a perfect example. Great benefit to the buyer, but through noise, pollution, taking up space etc. a bit of a nuisance to all others and making them more likely to also consume a car so as to at least participate in the benefits. This ends up in a situation where everyone gets locked into a net negative system where individual escape (dumping your own car) just makes you worse of as you just forego the individual benefit without any perceptual change in the collective negatives.

I find a motorcycle with lots of storage to be a nice compromise. Cheaper and more fun too.

Of course you do need to take a safety course and be aware of the dangers, but at least people acknowledge their danger. Cars somehow get a collective free pass despite their astronomical death tally.
