The morale there must be awful.

Yes, that must be it... they didn't think to break a window. Many modern cars use laminated glass on their side windows now and, as far as I'm aware, this model has doors that won't open from the outside without power, making them very difficult to break open without tools even when the vehicle isn't on fire. 20 minutes in to the Tesla burning, when it was already sitting on top of a bomb of a battery... you're beyond fucked at that point. Difficult to just put the fire out for responders, a rescue was over about 15 minutes prior.

Both great metrics to have, true.

No, there's no way to automatically make something become law. A successful petition just forces the European Commission to discuss it and potentially propose legislation. Even though it's not forcing anything to happen, there is an incentive for the commission to seriously consider it as there is probably a political cost to officially denying a motion that has proven that it concerns a large amount of people.
