Did Vancouver's experience result in a shift in transportation priorities long term? Or after the Olympics, were people eager to go back to the prior status quo?
The funding went away so things went back to normal. Of course with any available roadspace, it will be filled up and used. Later on with a new government transit funding increased and transit has subsequently been seeing double digit growth. The entire exercise makes me feel pretty confident that you can close off road space and so long as you're funding viable alternatives things are fine.
People take whatever is easiest, so in cities like LA it's no suprise that millions of people would rather sit in traffic hell for 45 minutes one way a day when their transit trip would be an hour and a half, if everything works.
If you want less people driving, then you need to provide a better alternative beyond transit just being the civically minded thing to do. It also doesn't help when its not perceived to be the most safe alternative, in terms of crime and harassment.
