Is Driving the Speed Limit Unsafe?

I did a little experiment on my way to work this morning.

I put my lead foot aside and actually drove the speed limit. It was frightening.

I have never been so anxious on the road in my life. People speeding past, cutting in front of you from on-ramps, tailgating...I'll be honest -- going the speed limit (at least on the Parkway) seems to make you a road hazard.

I got more than one dirty look today from passersby.

It seems to me that 'keeping with the flow of traffic', no matter what speed, is the best option...but if the flow is going 70, you're still breaking the law.

I'm not saying everyone should go flying down the highway at 90 mph, but it seems that 65 is not cutting it, and 55 is downright ignored.

Have you ever tried driving exactly how you're supposed to at all times? Hands always at 10 and 2, stopping for a full 2 seconds at stop signs, following 2-4 car lengths behind the car in front of you?

I understand why we should do these things, but the truth is, it's just not practical in everyday life. If you leave 4 car lengths between you and the car in front of you, it just means someone is going to move in front of you into that space.

And when's the last time anyone used their signals while doing a K-turn?

I'm willing to bet that no one follows every traffic law all the time. It just doesn't seem possible. Sometimes common sense seems safer than written law.

What's one traffic rule or law you never (or rarely) obey?
