Extreme caster (8* and more) will cause tire wear and is too much on a wet road with low profile will PUSH BAD.
Four degrees is very conservative.

Everybody needs "slalom" when that autonomous Tesla comes out of the side-street.......not just for autocross guys.

VERY simple explanation (there are other factors at work)::::Caster is the difference between shopping cart wheel flutter, and a bicycle when u push it along using the seat only. Caster being the angle of the head stem where the steering bearings are.
Thank you! I get it better now
