Failed twice consecutively. Aren’t the side glasses meant to be breakable by regulation for escaping situations when the door is jammed?

Two crazy theories: They'd been testing on the front and rear windows and someone thought it would scan better on stage to do the side.

Or if they've been testing on this exact car and repeated strikes delaminated the mylar layers enough for it to fail.

I think the explanation is much simpler, the guy threw it faster than it was falling in the earlier test. After ~8m (more than the 20-25 feet someone else estimated) the ball is only going ~45 km/h or ~28 mph which is pretty slow actually.

Yeah I was thinking about this. Would such a flub to forget only the windscreen was the new glass though.
