Naaa. Over-engineering would be putting a strain gauge in the parking
brake cable and building an electronic circuit to indicate when it is applying
tension on the shoes.
And once you do that you may as well put some speed sensors on there and an
ignition kill switch such that if you attempt to drive off with the brake
set it will kill the engine.
I'd be happy to develop a prototype if anyone is interested and has $15,000
to spare.
