Yes and no; if you're accusing unvaccinated-by-choice people of recklessly endangering others, then it's quite different whether they're endangering random other people or only other unvaccinated-by-choice people. (Similarly I have no problem with drivers on private car-only roads, only those who endanger pedestrians and cyclists on the public roads).

Also the dynamics of how far any given infection would spread are very different in a post-vaccination world.

Sure now your only recklessly endangering those who can't get vaccinated and those who opt in. So maybe at steady state the numbers do work out in favour of it being less dangerous than driving proportionally(excluding the people who opt in to this danger). But you realise we're talking about driving, an activity that actually accomplishes something, as opposed to not getting vaccinated which accomplishes at most nothing. If driving accomplished nothing you can bet you wouldn't be able to do it in the city were you are involving others it'd be relegated to tracks.

Technically, I was talking about drunk driving, which kills a lot fewer people than (productive) driving. That's why I selected the limited case of people who innocently die because of a driver's wilful negligence, which is exponentially fewer than those who die because of antivaxers' wilful negligence. Probably even when there isn't a pandemic with an R6 replication rate.
