Yeah, there is a difference between what's legal and what's smart. If you're going slow and somebody runs into you, it may be the other guys fault, but that doesn't change the fact that you got hit.

That being said, I'm in no way suggesting that you HAVE to drive the speed limit. I regulally dip down under 30 mph in 60 mph speed limit zones (during P&G). What I (and you) always have to be watching for is that idiot whose cruising along at 10 mph over the speed limit and not paying attention to traffic. In my case I have the advantage of driving a large white object, that's easier for people to see. I've had one or two "close calls"--where somebody obviously didn't see me until the last minute and had to swerve to miss me. In both cases, it was where there were 2 cars, both going too fast. The first guy was fine and passed me no problem, but it was the 2nd guy who was the idiot and wasn't paying attention.

Here's a few things I've learned: First, keep a close watch on your rearview mirror. You can tell if somebody is closing on you rapidly and not moving over to the passing lane. If that happens I either do a fake right turn signal (the blinking light gets their attention), or I just go ahead and do a pulse to get my speed up. Second, if there's more than one car coming up behind you then it's okay to go slower than the speed limit (10-15 mph under), but don't do any of the really slow driving--you're just asking for trouble if you do.

Another thing to remember is that techniques may need to change depending on the type of road. I drive a lot on 4 way divided highway, but it's not limited access (there are red lights and intersections) so people tend to pay more attention that out on the interestate where people are used to being able to run 10 mph over with the cruise control set and turn into zombies, not paying attention to what's going on around them.
