Probably those fancy electric and hybrid cars. In the meantime, I’ll be over here, clinging to my old gas-guzzling relic. Someday we’ll all be cruising in high-tech, earth saving, luxury SUVs.
I reckon velomobiles are a better option if you want to have pedals. Otherwise just make it a mini electric car.
Something like that would be awesome and solve a lot of problems, but it would need it's own infrastructure, like separate lanes. Don't want those on the motorway going 40kph, and would definitely not be good on the bike lanes either.
A brand new Prius starts at like $25k, which is about as cheap as a new car gets, I don't think hybrid cars necessarily fall into the category of "rich people things"
