As usual, the Tesla risk is not on the demand side (there is plenty of that) but on the supply side. If they have an issue with the roll-out, that will mean a guaranteed miss on delivery numbers this year in a repeat from last year. Overall it won't matter but short term, the stock will take a hit and possibly even remain with negative sentiment for a few months like they had this year.
We will have to agree to disagree here. Maybe it's because we see rain on a very frequent basis where I live, but a leaking car is simply not a usable car. Also, Tesla certainly will want to avoid any hint of media reports that due to latching issues the doors may open while the car is travelling. Even if those stories are without merit, like with the fire scare, it will impact perception and stock price.
