idunno, Corvette engineers? Motorhead's? Part of the reason Tesla jumped to such a huge EV lead was because they poached from NASA. Seems like several of the serious electric car wanabe's poach from Tesla now. .
To be fair, Tesla also poached a number of people from the automotive industry. Engineers tend to be a lot more adaptive than the auto industry as a whole.
Don't forget, these are the guys that reengineered a front engine car into a mid-engine car. I'm sure they love a challenge.
