If next beamng update is a manual ignition there should be battery wear. for example older car, beaters, etc. should have a crappier battery so starting is crappier or to the point the point the battery is toast so the car needs to be bump started. what about if you leave your lights on the battery will run low and the car needs to run a little bit so the battery will charge
There could be a way to tune the amount of life/charge left in the battery. Plus, bump starting may be cool, trying to push a Burnside with a dead battery to start it.
There is "more features mod" fixing this and also adding things like horn, stalling, forced to clutch while shifting, battery simulations, etc. Its a must-have for me to anyone who likes realism in BeamNG
