Wisconsin Public Radio: Wisconsin family sues Tesla over crash that killed 5
"...According to the lawsuit, the car lacked safety features that could have prevented its batteries from catching fire and causing an explosion — or at least could have slowed down the process long enough to give the passengers time to escape.
