I'm scared to do it now but there does seem to be a lot of other paranoid advice in the Owner's Manual so I'm not sure which bits to take seriously. This is true, you know, it is called compression lock. It does not quite important for front wheel or AWD since sudden ***** in torque - the car just go straight ahead, pushing, understeer. If you have compression lock in a RWD, without DSC/ESP, you will oversteer and get a skid... well it is in fact one of the technique on Drift video that people use to start a drift.
