I still don't get why the lack of a reset, no-repair option is stopping you from cruising. If it was really that bad for most cruisers, wouldn't there be many more complaints about on this forum than around 3 or so? Here's an out-of-the-box idea... the people complaining just can't stay away from the walls and they have nothing better to do than complain now that patch X is out and all the other cruise servers have updated. (Have they?)
If you crash into a red-and-white barrier at any sort of speed, given their current physics, you will most definitely have a very broken car anyway, how do you drive with it unrepaired?
What is cruising anyway? The name implies that it is going around in circles at non-racing speeds, in which case, even if you're using the red and white barriers, how on earth do you end up on your roof?!
