Some of the main issues I have are FPS and desync. I decided to spend a good amount of time testing out vehicles on an empty server with a friend. We decided to see what it would be like driving multiple vehicles around each other. To start, we drove a hatchback from the coast up north on an empty server that had just restarted... We both had constant 5 FPS the whole way. Also, about every 10 seconds the car would be teleported about 10 meters to the right or to the left. This occasionally resulted in us being teleported in to a pole, wall, etc, causing our car to break down. This all happened constantly for the whole time we were driving cars around (3 hours). We took a break, the server restarted once again. When we got back, it was very smooth... For about 3 minutes. But then the same issues I just described came back. Once we got another car the issues unsurprisingly got much worse. The same issues occurred, only this time, instead of teleporting in to poles and walls, we would teleport in to each other, and frequently do a few flips whilst flying in to the sky because of this. Another desync issue we found included us being teleported back up to 1000 meters. For instance, I was in Nadezhdino with a hatchback. I drove it to Cherno, and all of a sudden I got teleported back to Cherno. I drove back to Cherno, it happened again. This happened about 6 times before I decided to give up. To sum it all up, I believe cars are completely unusable right now. After driving them around all day with constant 5 FPS, I realized I probably would've gotten farther if I had just ran (not to mention I wouldn't have a major headache).
