There are many more ways that cars cause problems to our habitat much beyond carbon emission, they include: requiring roads which pave over local ecosystems and create heat islands and exasperates drainage, requiring large open parking lots which make a city less traversable in any form of transportation beside cars (but parking structures are better I suppose), creating noise pollution (a bit part of it is tire noise, EVs aren't silent at medium to high speeds), causing eutrophication and health issues when ablated tire particles get collected into runoff, also that cars are much deadlier per capita than most other forms of transportation like walking, biking, subway, airplane, (but safer than motorcycles if I remember correctly)
