I admit, sometimes I drive a car. When I do, I'm constantly amazed at the number of cyclists (or just people on bikes...) who are completely oblivious to my door! Of course I always check to make sure I'm not going to door someone after I park, but it seems crazy the way all these people put their lives in my hands. I ride in the city almost every day, and I'm always incredibly careful to stay out of the way of doors, cars leaving parking spaces, driveways, anything like that becaue I've had way to many close calls. How do all these people manage to stay alive?!?
