All true. But since people will always be using cars, for all sorts of reasons, better focus on our favorite mode of transport. Governments can steer the way cars are used around but particularly in cities, by putting a hefty price on entering the city in a (polluting) car. London already does. Ditto parking fees. Even better is to relate fees to vehicle footprint. Public Transport is of course the oldest form of ride- even vehicle sharing. PT is great during commuting hours, but awfully inefficient outside those hours. Better have companies like Uber fill in the blanks in cooperation with PT. But even they should seriously consider reducing car size, since the average ride-hail trip consists of 1.2 passenger. As far as car usage in general, we tend to think that we have come a long way with Tesla. Stock market darling Musk only tackled one aspect in personal mobility: emissions. There are at least EIGHT more challenges to go. Bottom line, as long as we’re not capable of “beam me up Scotty” from A to B, the transport mode will be a physical thing. It better be as space- and energy- efficient as possible. Cheers, Ralph
