For those of us who still drive the car to & from the track, an absolute "must have tool" is a Visa card w/ enough credit line to pay for having it hauled home after you blow it up.
Sad, but true.
No doubt. My Dad has a nice trailer he could come get me with but my driveway is steep and impossible to push a dead vehicle up. My plan(thankfully untested) has always been to have a rollback drop it in my garage if I tear it up too bad to drive home.
