Cars

There is always medium traffic on the road I take to (and back from) the UCSD. There is also usually heavy traffic on the I-5, 7 lane highway going in the same direction. Now what do you think that happens if they close the I-5 because of the bomb threat?
I'm faster home than people in cars...

Red light and driving

California is one of the states in the US where you can make a right turn against red light. Before you do that, you have to stop and yield to pedestrians and other vehicles. It sounds like an incredibly dangerous idea, but in fact, it smooths the traffic and is probably safer at the end.From the perspective of a bicyclist. When there is a car on my left when I go straight ahead, the car can pass me (turn right in front of my) and thus I don't have to be afraid of the car crossing my path when I have green light.
I guess it works because drivers are more careful and tolerant in comparison to what we can see in CR. Also, roads are wider, so I feel safe driving to school on bike, when I have to go a few kilometers along three line road (three lines are not enough for the name "highway" here).
P.S. I read the Driver's Handbook and I could not believe what I saw. First, I'm not sure that such thing even exists in CR. Second, it is not a list of rules, but list of thing you should do for your own safety, safety of other etc. Instead of looking like a list of threats, it reads like a list of recommendations that mostly make very good sense.
