I never really thought it through, but always wondered about a pressure switch under the seat in combination with a line lock mechanism. The pressure switch would attempt to prevent start ups and the line lock (even if they got the car started ) would prevent the car from rolling. That in and of itself would hinder loading onto a trailer. I actually thought of these two ideas for my Harley until I found out about four burly fella's loading a stolen Harley using straps and two four foot poles.
