I'm on the line between strong and fearless, and enthused and confident. I've been bike commuting since 1992, and am comfortable riding in any kind of traffic if necessary, but l prefer not to go on some of the busiest, high speed streets, if a more relaxed option is available. However it's more based on preference than fear.
What I actually fear more than cars, is ice. That's where I'm not fully in the hardcore group.
