We've got hybrid/electric cars now. We're getting self-driving cars. GPS is a pretty big deal, as well.
I don't see any of these things as a big deal in terms of the sort of advances that were made in transport hardware in the 20th century. Of course hybrid / electric cars are nice, but they haven't heralded a change in the nature of the car in the way that (for example) the jet engine changed the nature of the aeroplane.
Indeed cars are an excellent case in point - you could buy a well-preserved classic car from the early '60s that would work just as well as a modern car for all intents and purposes. It might not have computerised engine management, fuel injection or anti-skid brakes, and you might have to visit a petrol pump a bit more frequently but it would be a perfectly practical car. In some cases it would go faster than the one I have on the drive at the moment.
GPS is at least 34 years old; it was used in the Falklands War.
