I've consulted a member of Management about this and it has been decided that if you are to go so stupidly fast over a speed bump and wreck your vehicle, either by it flipping or by your crashing into a wall then it must be roleplayed. The reason behind this is because realistically, even if you were to attempt to drive over the bump at moderate speeds, your vehicle would stand a high change of becoming damaged. If you do not RP the consequences caused by the speed bump. Then you will receive administrative punishment. If you don't want to flip, then SLOW DOWN.
Exceptions to this can be made for very low vehicle such as the Flash that become damaged even when you go over the bump at speeds as low as 5-10 MPH. If this happens to you, then screenshot the incident and report it to a Lead Administrator.
