I'm going to make this short. Don't go into "Limp mode" "Stop the car!" Shut off the fuel or the ignition systems! Do you realize how much damage can be caused at 35/45 mph ? Car damage/personal property damage/ or worse "loss of a life". You have a great start. Listen to other suggetions and go from there. My last "soapbox reply"... I would reather have my cars put into a "Rock Crusher" than used as a deadly weapon ! Just my opinion.
