In the U.S. District Court for the Southern District of Florida, a jury has found Tesla 1% negligent in the death of an 18-year-old man whose Model S sedan slammed into a concrete wall after the car's speed limiter had been deactivated. The teenager and his father were found to be 99% at fault. The case is Riley v. Tesla, Inc., No. 20-CV-60517-VALLE, 2022 U.S. Dist. LEXIS 115266 (S.D. Fla. June 29, 2022).

Barrett Riley had been driving at 116 miles per hour, on a curve with a posted speed limit of 25 mph, on May 8, 2018. Riley lost control of his vehicle, a 2014 Model S, while trying to pass another vehicle. The Model S collided with a concrete wall and burst into flames. A second passenger also died but a third passenger survived the fiery crash.

James and Jenny Riley, the parents of deceased Barrett Riley, claimed that the crash occurred after a Tesla technician, without their knowledge, disabled a device that had been installed at their request, which capped the Model S's speed at 85mph.
