Did you know most vehicles have working turn signals? This is also true in BeamNG.drive! Use [action=toggle_left_signal] and [action=toggle_right_signal] to activate them.
Cars with more weight on the rear wheels can have a tendency to initially understeer with throttle application, and then oversteer suddenly. This is called "snap" oversteer.
Overheating coolant may vaporize, making a hot engine harder to cool down after long periods of overheating. You can recover the vehicle using [action=recover_vehicle] to reset the coolant level.
It's not a good idea to sprint at full speed into cars. This applies not only to real life, but also to BeamNG.Drive. You can damage the car by doing it.
