I just spent the day watching a local drift event. I rode my bike there and it was awesome. For the nerds: my two favorite cars there were a 3SGE-swapped TE72 Corolla and an S14 with a RB dry sump setup.
Commuting? general transportation? Cars are completely unnecessary. For motorsports, however, cars ARE necessary. What are you gonna do, drift a bike?
A glimpse into the brain of a car enthusiast that hates cars.
Private cars should not be abolished by just issuing a ban or raising taxes on gas.
Cars should be abolished by changing the way city planning is done, so people will be living in biking-sized neighborhoods, containing housing, workplaces, and the services you need every day like a supermarket, a school etc.
Also priorities should be shifted from building and maintaining roads towards building and maintaining public transit infrastructure.
