	Thanks.  This is surely the intent, make BGP safer for
all involved.  The interesting bit here is that some implementions
don't even have the capability to apply the brake pedal prior to
the vehicle moving.  This of course makes it easy to move, but
much harder to stop (and undo the collateral damage).
