LOL, not quite. In 2013 Tesla built 20K cars, were not focused on profitability, had a completely different build process, and the reputation of those models were already "mechanics' worst nightmare" if repairs were needed. Your expectation of in-depth reasoning on how the issues of limited series early cars differ from the post post-Alien Dreadnaught era's cars produced at 100x the volume implies that this is a wasted effort.
You seem to equate risks of ownership with safety. Most of us won't drive off a cliff in an attempt of murder-suicide... or even be t-boned by a pickup. Most of us however, will have to deal with car maintenance at one point. So the real risk of buying an older tesla without warranty is unexpected repairs. Or as
@VW TECHNICIAN eloquently explained the cost of using cast aluminum is very high body repair costs. Overall these make the maintenance of a Tesla much costlier and the insuring it x2 as expensive than most other cars of the price range (or above).
