Nope, watch the whole Whistlin Diesel video. They DID smash the tow hitch with a large perpendicular force prior to the breaking, but it was in fact the cast aluminum frame that broke. While this was a torture test with conditions not encountered by regular users, the failure supposedly happened at least once in the field with someone whose trailer hit a pothole. Since cast aluminum tends to crack rather than bend, this has the potential happen even more when the trucks are subjected to smaller stresses over time as people tow.
Oh wow. That is crazy it has passed regulations. I mean OK its not 'normal' use but still shocking.
I think regulators will force Tesla to reduce the tow rating at least.
