When the majority of Americans dislike and/or are unhappy with 100° Thanksgiving, beepocalypse, aging out of being able to drive, or whatever else “cars” wreck, then they will start voting to push the externalities off to heavier users.
Eventually, the resulting ghost sprawl of empty suburban neighborhoods will provide enough recyclable building materials to rehome us all nicely in subterranean hive cities. Our eyes will evolve larger to gather the dim light. Our ears will shrink to muffle the incessant hum. Our useless teeth will disappear after a few centuries of microbial food paste consumption. Clothing will become an affectation.
Alternatives are important here since while most Americans drive that doesn’t mean that they love everything about it and won’t consider alternatives. There are a ton of people who would love not to pay thousands of dollars to sit in traffic and make their health worse, but they don’t see a good alternative. The activists getting bike infrastructure, improved buses, and density are giving them that option and climate change is causing a lot of younger people to realize that the timing has to be stepped a lot since even EVs produce more CO2 than any other form of ground transportation.
There’s big generational component here, too. Most drivers aren’t old enough to think of roads without traffic as normal, and economic trends mean that a lot of younger people are faced with even longer commutes in cars, not to mention that transit is more appealing when you have smartphones.
1. In addition ti the obvious one of pollution, housing & retail prices are high due to requirements to provide subsidized parking to drivers. Removing that allows owners to make different decisions.
I personally think urban development should be more expensive to cover its externalities (i.e. forcing people to buy cars because of landowner-enriching sprawl).
Get your politicians to call my politicians.
