With this patch it feels like you have increased the amount of resistance a defending vehicle has to low/medium impact collisions.
Feels like there is also a reduced amount of reaction to impact force, for the attacker, in all collisions. And the friction between vehicles is near to zero.
Which makes side by side racing easier and accidental spins/blockages rarer.
These things also make defending cars hard to spin/move unless you ram, and when you ram there little consequence/risk to yourself unless you hit a static object.
In racing context this means diving up the inside line is the easy option. Wall ride on players. Defend just by holding the inside line. If they try overtake on the outside, lean.
There is very little the other driver can do, other than the same tactics, since you are hard to spin.
Overall there is little to no physical reaction in small to medium hits for either party. The collisions are mostly flat or vertical bounce which feel/look underwhelming, like crashing blocks of ice. Until you reach a threshold where the defending car becomes almost a low mass collision object. Bouncing around like its gone low gravity/mass.
This mostly happens when squeezed, making the defending car look like a 'squeezed bar of soap' flying in the air. Or you drive through/over/under people and the cars become ramps.
It makes crashing cheap, control less and risk free. And doesn't look or feel realistic or good. The previous build was better for all of the above in terms of collisions, other than 'squeezing a bar of soap' which hasn't changed.
