A quick look at the devastating result of excessive speed: Professional golf legend Tiger Woods is home recovering from critical injuries sustained when his SUV went off the road striking a hefty sign and trees. Woods concedes he doesn’t know exactly what happened or how fast he was going. So armed with information downloaded from the vehicle event data recorder (EDR), the investigating officer told Woods what happened. Tiger Woods now understands how fast he was driving, reaching 80 MPH. I bring this up because it is a good example of how rattled a motorist can be when involved in a severe traffic crash. Drivers earnestly try to tell crash investigators what happened, but it quickly becomes apparent to the officer the poor guy doesn’t really know what happened. So after downloading the data from the EDR we can share with the vehicle operator precisely what did happened.
