Non-car modes of powered transit - small petro scooters, e-bikes, etc.
People always need to get around in a non sweaty way but a car is both a lead weight financially and a potential windfall when car prices are artificially high.
I don't see these being true unless you live in an area where getting around on a bike is actually realistic. Basically not USA, even the metro areas, except for maybe a handful.
I lived in a van with an e-bike for a year and traveled the United States extensively in both modes. I can assure you that getting around on an e-bike is realistic pretty much everywhere in USA. Even over long distances or hilly terrain or in the hot or in the cold. I agree that the comfort of the car makes people 'soft' and so entrepreneurs looking to sell alternative modes of transport need to work hard at allaying the concerns that you imply with your worldview if they want to get customers out of cars.
