&gt; It also is very sensitive to resistance, to the point that I actually had to construct ramps for my car to climb the 1-inch lip at the entrance to my garage, otherwise it would stop at that point and refuse to go further.<p>The pictures of the car in a article linked elsewhere in this discussion (<a href="https:&#x2F;&#x2F;www.ksl.com&#x2F;?sid=39727592&amp;nid=148&amp;title=utah-man-says-tesla-car-started-on-its-own-crashed-into-trailer" rel="nofollow">https:&#x2F;&#x2F;www.ksl.com&#x2F;?sid=39727592&amp;nid=148&amp;title=utah-man-say...</a>) show that the windshield was smashed.  I&#x27;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.<p>&gt; but I don&#x27;t think there&#x27;s much room to discuss safety here.<p>I couldn&#x27;t disagree more.  I don&#x27;t understand why it should be possible to disable any safety interlock (at least, that&#x27;s how I&#x27;m interpreting the feature description) in a consumer product, especially persistently.
