A Tesla Roadster, driven by Tesla's Director of Sales, was wrecked in a demonstration gone wrong. He took a turn at 100MPH on a wet road with low visibility and lost control. Remarkably, neither the driver nor the passenger (who was ejected from the car) were seriously injured. According to Wrecked Exotics, this is the 3rd accident involving the Tesla Roadster and none have resulted in serious injuries.
Thankfully Tesla has built passive and active safety systems into the Roadster's Li-ion battery to prevent thermal runaway (aka explosion), unlike Sony batteries.
