The level of car blindness in the US is at such insane levels that any advocacy for living that isn't car dependent is pretty much a completely radical take that people reject out of hand. So political movement is often limited more by what is possible rather than what the right course of action is.

But these are not equivalent things, cars are nowhere near as deadly as Covid, this pandemic is likely going to cause 25 years' worth of car deaths because of a subset of the population is too morally and logically weak to adopt small measures.
