Cars are getting bigger and so are the other vehicles on the roads .... HUGE lorries, transporters, safety vehicles, etc, etc. I certainly don’t want to go back to the first car my father had, which I was a passenger in, which was very lacking in seat belts, air cushions and decent braking!
What we really need, of course, is a massive investment in public transport, buses, trains and (why not) canals? Then people won’t need to be so dependent on their 4x4s, old Saab’s, microminis or whatever!
Some younger people are shunning car driving and see the value in an improved system of transport for everyone. ?
