Perhaps there's another solution here. Today's traffic is mainly moving *people* around. Perhaps we can reduce/replace those trips.
The last one on your list is a good example: going to a movie. The vast majority of movies I see now are in my home. I don't go to the movie theater. Didn't even drive to a BlockBuster. No travel involved at all.
Other things are harder to replace, but we're getting there. With technology, having lunch or your shopping delivered is becoming a practical option- and there's a lot more delivery options for a small package than a car full of humans.
