Greetings, I would love to see Beamng Devs nail the handbrake in the game. what the issue is when you pull the handbrake the Engine's RPM instaint dies and goes idle right away, which is not the case in real life. IMO this will improve the handling and adds a lot to the feeling of the car.
which wheels are driven, and is it an auto or manual gearbox in the car you're using? if it's a manual and RWD, you'll need to put the clutch in to lock up the rear wheels, or you will also stall the engine.
I'm talking about a manual gearbox, in RL you don't have to hit the clutch while you are pulling the handbrake when the car is moving and it's on gear.
With a RWD car, if you lock the rear wheels with the handbrake, you need to use the clutch or you're going to stall. It's the same thing with cars that don't have ABS when locking the wheel. I stalled my previous shitbox a couple of times that way.
