"Have you ever seen a bricked Tesla driving down the road?..."

I'm having trouble making any sense whatsoever out of this paragraph. It does not appear to bear any relationship whatsoever to Tesla OTAs. They don't apply while you're driving. The vehicle must be in park and is inaccessible until the OTA has successfully completed. If for whatever reason the update can't complete successfully, the vehicle rolls back to its previous software version.

Driving a "bricked" Tesla isn't a thing. Worrying about not being in cell range isn't a thing. Installing an OTA does not involve any kind of act of "turning the car on and off again".
