A pet opinion of mine - one of many I shall be airing here.
I'd like to totally ban private cars, vans, trucks. Why do we have them? They are patently unnecessary. I don't drive and I get to work by train and bus. Any function of personal transport not fulfilled by train and bus can be fulfilled by taxi.
Take a few years, redeploy the auto workers on rebuilding our railways and we would need no more freight lorries either. Imagine the quiet, the tranquillity, the fresh air. No more traffic jams, no more road rage, no more RTAs. Numerous social evils wiped out at a stroke. Jobs on the railways for hundreds.
