Yes, I agree. Two scenarios:
1 - A kid is killed because the controller closed spuriously. First, someone would have to prove the controller closed spuriously, as opposed to the kid or someone else activating it. Then, they'd probably have to show that it was caused by a specific design flaw that the manufacturer knew or should have known about as opposed to some random component failure that couldn't be anticipated. 2 - Same thing, but activated by someone's controller down the street. Extremely unlikely with today's controllers that use pseudo- random codes. And if it happened to occur, what's the chance you could establish that's how it happened, exactly who's controller did it, etc? 3 - Door closes after 2 hr delay as provided for by the maunfacturer and kills kid. Or kid just sticks his finger in between door sections and gets it crushed, for which there is no effective safety emergency stop. In this case, you have a case where the manufacturer designed it to allow it to close unattended.Which case do you think is easier to prove/win?
