Not true. The Tesla Musk bought was a fledgling primitive company with practically nothing in common with today’s Tesla. What about Space X ? The Boring Company ? Starlink ? Did he buy those too ?
The Tesla of today is now considered one of the most dangerous cars on the road, having a crash rate more than double the average. Tesla's best vehicles were made by that "primitive company," and it is thanks to those early engineers that Tesla became as successful as it was.
