I wonder what exactly will happen to all the cars if Tesla goes completely bust. I remember when SAAB fell over, their cars took ~10% depreciation and a noticeable insurance bump overnight. For a car company that vehemently blocks third parties from doing maintenance on their cars, and with a big complex software at the heart of the vehicle, I wonder just how big of a financial loss it could end up being for Tesla owners. Might we see 50% value loss overnight? If no garage has the tools, software and knowhow to fix it, what do you do when it breaks?
