Canada needs more roundabouts.
Canadians can't handle roundabouts. I was going around one on the weekend when the minivan in front of me stopped in the middle of the roundabout to allow someone to get on in front of them.
She probably had no idea why I honked at her for blocking traffic and almost causing me to get rear-ended.
Same here, woman shook her head at me for beeping her when she pulled out in front of me. People have no idea, and it seems, no intention to learn...
I drive through a roundabout every morning on my way to work, and I can count on one hand the number of times I've seen someone use their turn signal to indicate they're about to leave the roundabout.
And since nobody knows whether that car coming at them in the roundabout is about to exit or keep going around, I guess they figure they need to come to a full stop when trying to enter the roundabout, even though it's clearly marked with a Yield sign. Better be safe and just sit there and wait until the roundabout is totally clear of traffic.

I think roundabouts are the best thing ever, but if nobody is going to bother to learn how to use them, we're probably just better off with the old four-way stop.
