I try to go through or into LA at about 3am. There is less traffic then. I hope they're headed to a fringe community and not actually into the heart of the place. It's bad enough in a car: in a U-Haul - oy.

I think you might have to buy extra roadside insurance from UHaul, but when there is something like a flat that is their equipment to fix, I'd guess. I have AAA and I cover my children with it as well. Even though they don't own cars, as passengers if they run into problems they can call for a tow truck or tire repair, etc. My daughter has had to use it a couple of times with the funky vehicles her roommates were driving at one point.

Anyway, LA is so large, if you can narrow it down we might be able to offer more observations (if not help). :)
