I've met some interesting drivers at Uber. One had a restaurant chain that he had sold off and was killing time. No Tesla yet but a 7 series BMW and a high end Mercedes. I've also spoken to many Uber drivers who were blue collar works in the Bay area and have houses worth over a million bucks ... they have little income so Uber allows them to stay in the Bay area.
Any way to verify the claims from the article? I can't find any mention of Rivalta or its sale to Salesforce. Seems more likely the Tesla is leased (business expense) and he spends more time as an UberBlack driver to pay for it.
