They might require the passenger to sit in the drivers seat and take liability, or push it back a few more months, or only run it at 3AM when there is no traffic.
I don't think any of these would tank the stock price, since historically Tesla has gotten away with similar skulduggery. I learned the hard way many years ago to not bet against Tesla, and I don't see anything here that would override that lesson.
Fingers crossed for you though - I definitely think Tesla is irrationally priced, and there would be a certain justice in that overinflated valuation sinking down to reality.
