That would be fine except that cars release poison into the air, old cars especially. Eventually banning ICE cars is an essential public health measure.
That's a shame because there are some remarkable cars, both modern and classic, that will no longer be able to drive on the roads if we ban all ICE.
It would be the equivalent of banning steam engines, which although no longer in normal use, are still running as tourist attractions and remarkable pieces of engineering that are fantastic to see and experience.
No real need to ban old cars, they tend to quickly phase out on their own. Heck, the state I live in has uninstalled all the expensive dyno equipment they used for pre-OBD2 cars because there just aren't enough left on the road to justify maintaining the test. They still sniff, because that's cheap, but not on a dyno.
Given that we still allow horses and Model T's on the roads (aside from freeways, due to inability of century-old cars to maintain that speed), I can't imagine why we'd bother banning them. The nostalgia is nice and their impact is negligible.
Both policies exist actually. For instance old cars and motorcycles are getting banned in Paris (outside of weekends IIRC). Even if as the grandparent points out making a new car generates a lot of pollution at least it would reduce the more local problem of having a heavy smog on windless days (and all the health issues that go along with it).
Banning old cars from inner-city driving is a nessesity. With how densly cities pack both cars and buildings, suspended particulate matter is a serious public health risk. But we can still allow them everywhere else where we aren't already struggling with keeping particluate levels at a reasonably safe level.
Ya I'm visiting my mum in a rural area and I went for a jog today and I couldn't believe how bad the exhausts were that drove past me. I don't think they'd pass the emissions test in the city I'm from.
The irony is that the state that loves to pat itself on its back for being so environmentally conscious is also that last state where you could buy leaded gas in the U.S.
