Just found a solution for driving regarding the freezes, drive in first person with your head facing slightly up (still able to see road obviously) it seems the only option right now.

Big problems with FPS in towns when driving or just driving in general, the funny thing is the lag isn’t there for any of the passengers, only the driver. This can cause major time wasted when building a car takes a long time and can just be thrown away by 1 crash due to FPS/freezing. There should at least be a way to fix a car when damaged, instead of it just de-spawning after 5 minutes.
