ICE cars are not just problematic because of their emissions, they do much worse things with their infrastructure requirements. Roads and parking that can support everyone driving their car alone everywhere results in sprawl. That makes everyone not in a car have to get in a car as well, and also increases infrastructure costs for other services, since they have to service a much larger area.
Cars have their place, but in an ideal world, a regular family regardless of where they live shouldn’t need one. It’s not a personal mobility solution. Taxies and stuff make sense, everyone sitting in their own car doesn’t.
And this is not even counting that car accidents are a leading cause of fatalities because we give a licence to everyone with a pulse.
