High speed driving is unlawful and just poor judgment here in the U.S. This form of driving should only be done in a controlled environment such as the track. This thread only encourages such immature practices. That said.....
127 on I-95 a little North of Baltimore.

ops: I had a nice (but rare) gap in traffic late one morning allowing me enough time to accelerate before catching the cars in front of me. I generally don't like passing non-participant motorists at too fast a clip because you can't be sure of an unexpected lane change, etc.
