We don’t all need vehicles. But we probably do need some vehicles as a society. When my brother wants to haul in soil or haul out yard waste, or when I want to get furniture from IKEA, we’re going to want a truck. But there’s no reason for either of us to own a truck for those things we do only a few days a year. Some combination of rentals, a car/truck share program, or an Uber style of thing fills out needs. And on the other hand, my father needs to haul a large trailer full of equipment around the province on a daily basis - he absolutely needs a truck.

London in the 1850s had about 10,000 private vehicles for a population of 1,000,000. People took the autobus, the trains, or just walked. If we could get to the point where less than 5% of the population had a personal vehicle, we’d be doing pretty good and could cut out a lot of CO2 emissions.
