Not that I've heard of.  Some even have tilt switches to set the alarm off
if that happens.

They're not terribly useful because everyone ignores them, and the good
thieves know how to bypass the starter disable features.  Generally they
just disconnect the key switch with a relay under the dash, the car can
still be hotwired under the hood or bump-started.
