I commute everyday, and have been doing this for over 20 years. This makes it around 40 cyclist killed this year by cars in Southern Calif. All you can do is keep your head up, be aware of your surroundings, and never assume that the car pulling out sees you. Always be aware of cars passing you from behind. If its narrow and there are two lanes going in your direction, take the whole right land. Make the car passing you change lanes. I also ride with a club in groups on the weekend. Cyclist who don't obey traffic laws, who are rude to motorist, make it hard on the rest of us. Even though you might have the right of way, you will lose with a collision with a car. Be Safe out there.
