What one ignores is the traffic that you pass when you're going 65 in a 55. I would estimate probably 1/4 of traffic is moving at or just below the limit. I'm in Houston and we deal with traffic quite a bit and I'm not addressing rush hour bumper to bumper here. The fundamental question is who is at fault for the differential in speed (i.e. that which increases risk of injury/death with an accident)? The answer is the person who breaks the law and the one who does so as a precaution to themselves (i.e. following the flow of traffic). An accident by this group disproportionately affects those obeying the law. So I see three groups. 1. The speeder. 2. The law abiding citizen. 3. The person who is aware of their surroundings and adapts. Ethically between 1 and 2, 2 has the upper hand. 3, when driving with 1 increases risk to 2. But if 3 joins 2 they increase risk to themselves and to the larger group 1.
