When talking about the economics of Tesla’s future fleet of robotaxis at the Tesla Autonomy Event, Tesla CEO Elon Musk emphasized that the vehicles need to be durable in order for the economics to work:

“The cars currently built are all designed for a million miles of operation. The drive unit is design, tested, and validated for 1 million miles of operation.”

But the CEO admitted that the battery packs are not built to last 1 million miles.
