I don’t think it makes sense to completely abolish cars. There will always be transport needs where public transport, trains, or bicycles just don’t fit the bill. There will be car and racing enthusiasts for the next century (assume we don’t collapse). The car industry needs to be reduced by 99% though, mostly transforming into maintaining existing cars rather than producing new ones.
Some people will want to or need to live or work where public transit systems would be impractical to build. You can’t spend 80 million dollars on a transit system out in the sticks and you can’t force everyone to live like sardines next to a bus stop.
