The driver of the 2021 Toyota Sienna said he crashed because another car bumped the rear of his vehicle while passing on the right, causing him to lose control.

It was the wrong car for lying about the cause of an accident.

Timothy Staab, owner of Delta Analysis, said most late-model Toyota and Lexus models are equipped with vehicle control history (VCH), which adds an extra level of data in addition to the event data recorders (EDR) that are now standard equipment in almost all automobiles.

Staab, a retired police chief who now makes his living investigating vehicle accidents for insurers, was among several experts who spoke Wednesday about the promise of technology at the Combined Claims Conference. Staab’s presentation focused specifically on how the safety devices in today’s cars offer a fountain of data that can be tapped to reconstruct accidents.
