Elon Musk's legacy is closely tied to the fate of his electric car company. But so is that of his brother.
Elon's brother Kimbal is also a Tesla board member, and he had a lot to lose during the Great Recession.
"This was in 2008," Kimbal recalls. "I mean, everyone thought the world was collapsing." Dealing with product delays, recalls, and a shortage of funds, Tesla looked like it could have followed General Motors and many other niche automakers over the years into bankruptcy.
