Car tires too need to become biodegradable. And we need to make cars that last twice as long in daily use. And we need all the charging infrastructure. Battery recycling. Noise barriers on every highway to save the wild bees. Green parking buildings that don't soak up heat in cities like large lots do.

The list of stuff that has to be done can keep growing. Can't communicate all that to someone who doesn't want to listen, so we have to communicate "ban cars" and wait for people to afford the attention span required. It's not a clean and simple business.
