In a recent update improvements to oil simulation was implemented making oil starvation occur more realistically when jumping or rolling your vehicle in the game. The improvement I suggest for a future game feature would be for Batteries to behave more realistically. In this case if the battery were to take impact there is a chance it could disable the vehicle as such in real life. A battery being knocked out of a vehicle in a collision would render it disabled and loose function of everything such as steering/power steering, engine, lights, other vital components etc. This would be a nice touch of realism to occur for those who love crashing and in general to how in depth the simulation in BeamNG is.
