I doubt there will be a lot of change. Car pool type groups are an option for those who use taxis a lot but many of us like to own our own things, and to keep some of our possessions in our car where they are handy.
I see little benefit to trams at all let alone giving up road space for their own use. That's as bad as bus lanes, but more expensive. I can't believe anyone would seriously suggest there is a possibility of having driverless car lanes; even 200 mph ones, which would be too dangerous for other road users, even if they otherwise have a good safety record.
Automatic cars did not have the massive change some predicted when they first came out. Still plenty of manual drives about. Driverless ones will have much the same minimal affect even if, over a long time, private cars will gain a bigger share of the private vehicle market.
