A comment on riding speed. Most car on bike crashes that have happened to my friends and family members occurred at intersections when the cyclist was riding fast and the driver "didn't see" the cyclist. Whenever approaching a particularly dangerous intersection, I'd recommend slowing down a little. An oncoming car making a left turn, for example, may not realize that you are riding 25 mph. Interestingly, bikeshare crash rates tend to be lower than overall cyclist crash rates. There are different theories to this, but I attribute it to the slow top speed of bikeshare bikes. To my knowledge there have been ZERO bikeshare fatalities anywhere in the US. Cities like Boston and DC have already logged over a million trips with not one fatality. Quite impressive.
