Basically cars enjoy teleporting at random and will sometimes get launched into the air if they hit something, and if a player with bad ping or they crash while in the passenger seat the car actually becomes some sort of house of horrors because it will just... twitch i guess? it starts to rapidly fling itself all over the place and sometimes it goes through the ground, but it always ends with your car launching itself to outer space or flinging itself into a wall and you dying and about the teleporting car thing it's not lag on my end or FPS drops (which do happen with vehicles i go from 100 FPS to 1 and so does many friends of mine) the car will just stop for a split milisecond and then 2 outcomes can happen A: the car randomly teleports to either the right or left ending with the car doing rolls and ending your life and B: it will start moving again but the speed jolts as if you put a rocket on the back and turned it on, usually ending in the car over revving (which needs some work because over revving doesn't damage a car over time it would damage it after a long period of continued over revving) and breaking down or you spinning out and hitting something
