The issue with this is the bots occupy the vehicles. So when the vehicle I'm practicing in gets destroyed/I crash it, it's quicker to quit to the main menu and start a match again, than it is to wait until the vehicle I want becomes free...which feels like a silly thing to have to do.
It's what has turned me off playing the game more. In Bat4 and V, I could practice and crash over, and over again, and it lead me to enjoying more ways to play those games.
If 2042 had the option to turn bots off I personally would be happy with that, although I can still understand others wanting a dedicated practice range like in Bat4.
