Use Electric Parking Brake for Toad Break-away ? ? ?

I must be missing something. My understanding is that the breakaway system is to apply the brakes on the toad in the event of a breakway. The safety chains are to maintain control of the toad until you can get safely stopped. The idea of a breakaway toad crashing either into a ditch or to someone else is frightening.

Homegrowing a safety system gives you the benefit of the liability if it fails.
