I’ve occasionally blogged about EDRs or “black box recorders” in cars. But have you ever seen their output or a report from one? I hadn’t. The Boston Globe published one such report after Massachusetts’ Lieutenant Governor Timothy P. Murray was in an accident in a state vehicle. The findings contradicted his previous statements about the accident.
Anyway, you can read the report here. And do note the disclaimer section about what the instruments record and don’t record – and how crash reconstructionists need to be aware of certain limitations.
