-- Emergency Brakes: As a driver of a vehicle, press your flashlight/q button to apply emergency brakes
-- braking multipliers added for stability during braking.
-- Note: holding the emergency brake may make it appear to lag or lurch, should only be pressed once, not held down.

-- If this is set to true then emergency brakes are enabled.
