(Reuters) -A Florida judge found "reasonable evidence" that Tesla Chief Executive Elon Musk and other managers knew the automaker's vehicles had a defective Autopilot system but still allowed the cars to be driven unsafely, according to a ruling. Judge Reid Scott, in the Circuit Court for Palm Beach County, ruled last week that the plaintiff in a lawsuit over a fatal crash could proceed to trial and bring punitive damages claims against Tesla for intentional misconduct and gross negligence. The ruling is a setback for Tesla after the company won two product liability trials in California earlier this year over the Autopilot driver assistant system.
