What people usually attribute to bad driving is usually the fault of poor traffic planning. Humans tend to be the same, circumstances change.

I wholeheartedly agree that we should increase driving standards, and better traffic engineering is the first step. I was just commenting on the fact that most people I talk to don't want to learn how to make their morning commute safer and more efficient.

It was terrible the first few years. Nobody could ever figure out which lane they were supposed to be in, and ended up driving on the wrong side of the crossed-over section. Granted, the people here are still having trouble figuring out roundabouts, but I found this very confusing my first couple times through the intersection.
It's not very confusing exiting the highway and turning left - just follow the lights.
It is kind of confusing exiting the highway and turning right. Right-on-red is allowed, and to make such a maneuver you have to look in strange places for traffic that might hit you. I've almost messed it up a few times. The other option is to let people honk at you while you wait for a green.
I'm curious as to what will happen when the power to the lights fails.
I could see there being less accidents of the left-turn variety being exchanged for more less-dramatic accidents.
Aren't we better of just using roundabouts? or http://en.wikipedia.org/wiki/Roundabout#Turbo_roundabouts??
