Tesla considering two theories that may explain fatal Model S crash

Tesla is considering whether the radar failed to detect the truck or detected it but 'tuned it out' as a structure such as a bridge to avoid triggering braking

Tesla Motors told the US Senate commerce committee staff it is considering two theories that may explain what led to the 7 May fatal crash that killed a Florida man who was using the car's Autopilot system, a person familiar with the meeting told Reuters on Friday.

Tesla staff members told congressional aides at a briefing on Thursday that they are still trying to understand the "system failure" that led to the crash, the source said.
