Hi, Cars internal health damage should be reduced to zero do to server regular lagging issues, resulting on you hitting an object and damaging your car internal health.

I believe is already good enough with car parts damage from normal use.

or at least add bicycles, or motorcycle, or a self driven train to make it easer to get around the map.

once again, thanks for your time and efforts on fixing the game, so far is getting better, one step at the time.
