Auto x guys: Really need help, Tell me about a "technique' Options

[aircooledboy]

We have a case in my office were there is some question as to why a driver did something in an accident, and I really need to understand it.

The reconstruction has been completed and it appears that one of the cars in this "aggressive driving" scenario lost control during a maneuver wherein he applied the emergency brake on rear wheel drive car (late model Saleen Mustang) at about 80 mph while passing in tight traffic.

Can anybody tell me if here is some legit (or illegit for that matter) driving technique which would explain that?

Thanks

You guys rock as always.

Thanks for all the ideas. Hadn't considered possibility that passenger did it, which is not out of the question.

Interestingly, BTW, brake lights do not light up here, since we have black box data, and brake circuit inputs are negative. We know that the back brakes were locked up though by the skid marks.

Still glad to hear anyone else's idea.

Thanks again.
