Depending on your perspective here, the driver who hit the Tesla Model X was either at the right place at the right time or the wrong place at the wrong time. Thankfully for the Tesla owner and the authorities, the accident happened right in front of a police officer near a parade roadblock, so the response was rather immediate.
As you can see in the video footage above, cars were progressing down a residential street toward a parade roadblock. The TeslaCam clip shows cars on a two-way street in front of upscale homes in a New Jersey town, and the traffic appears to be slowing.
