If you get too near to another object the car you're driving will automatically break to prevent the crash(you can turn it of if you want) https://www.youtube.com/watch?feature=player_detailpage&v=ih2qTiqBhdA
Actually , it's a pretty good idea , but crashes will only happen in high-speed and so what is the purpose of jbeaming all this time ?
Really? I hope someone makes a mod for this or gabester implement it in the game. But that could take a very long time sadly D: - - - Updated - - - The car will impact at a lower speed because of the "system" which will make less damage
