Having one of those, from England and not Japan, they are less bad for the environment than one might think. You just don't drive them as much, gas milleage takes care of that. Being classics, you don't drive in winter with salt on the road. And you keep them on the road far longer than they were intended, no new car is a net positive.
Well obviously the less you use a car the less environmental damage it does, but if you're not driving it half the year then it's probably not displacing a new car purchase.
What I love about the “movement” (just like in CAlifornian Politics!) is that everyone is terrible if they try to actually do anything useful, but everyone is great if they do random stuff that wastes time and effort without accomplishing it’s stated goals - as long as it seems futurist and green.
It’s basically the now is unacceptable, and the future is impossible.
