“Tesla, because they are vertically integrated, they’ll move up faster than someone who has tons of suppliers. And the reason for that is because every supplier is on a payroll and they all want to get going because they want to make sure they keep a paycheck,” according to a very influential individual in the auto industry.
He also noted that
“You can only move as fast as whoever the slowest supplier is, and you’re only going to be as good as the worst quality supplier”
P.S. yes, you should prepare to long Tesla... when the time is right.
