Please fix this. It makes the game not worth playing

Me and my friend decided to go "out" with a car and we were saying "we'll be back on the coast in 2 minutes with this lag, guess what ! I was driving the car when I got kicked out (because it seems, a lot of players get kicked when it's too laggy), the car went into a tree because I got kicked, got to respawn and my friend was badly injured. I can't believe it, 10 years of development, I can't believe those "devs" can't make a stable fucking game in 10 years and are still adding shit update after update when we're asking for good stuff like diverse weapons, base building equipement, new vehicules but no, there are cheaters, desynch with the server and they are adding new "sounds" to weapons. Amazing.
