When my friend drove me to pick up my new Model 3, we made sure to find and test the alternative release mechanisms. The worst part is that the company and the car itself warns against using that in non-emergencies because it can damage the window trim. So basically you are strongly advised against trying out a critical safety feature because of poor design.

But we did it anyway, because a) I believe the engineering philosophy "if it's not tested it doesn't work," is especially pertinent for safety critical systems; and b) my friend told me of a couple of youths who had died just a couple days earlier in a burning Tesla because the electronics shut down and they could not figure out the alternate release mechanism.

Then he said, "Welp, enjoy your new car!" and drove away in his Tesla.
