The pictures of the car in a article linked elsewhere in this discussion (https://www.ksl.com/?sid=39727592&nid=148&title=utah-man-say...) show that the windshield was smashed. I'm finding it challenging to reconcile your personal example with the images of the smashed windshield; in my own experience, it takes some effort to break laminated safety glass. I would think (perhaps wrongly) that it would take more effort to break safety glass than would be stopped by a 1in. step.

I couldn't disagree more. I don't understand why it should be possible to disable any safety interlock (at least, that's how I'm interpreting the feature description) in a consumer product, especially persistently.
