I was a bit pessimistic about this being possible, but to see that we did this in the 1984 Olympics without any light rail is pretty amazing to hear.
You have 4 years. Not enough to start and complete a new rail project. So stock up on bollards and lane dividers. And start creating a physically separated bus lane on every major street right now.
LA? Car free LA?
I was in LA last summer. Not sure there would be anything left if you removed the cars and roads.
You should have left the freeway… There’s a lot of things in la other than freeways.
Look at LA with Google Earth and then compare it to a city like Berlin or München. You will see that LA has far more parking lots, more stroads (roads that extremely dangerous and hostile to pedestrians and cyclists), and far fewer parks
