I ride on a great bike lane for the first 3 miles of my commute. It's protected on one side by a curbed train track, with the lane to the other side being an "access lane" with a 20 mph speed limit. Then I turn onto a road that is a 40mph speed limit with no bike lane, a rough ass road, and some very bad Phoenix drivers. I hate this part of my commute and I'm quite sure that someday I'm going to be hit or crash, but it's only 1.5 miles. The remaining 8 miles is awesome... two lane road with a wide bike lane and lots of climbs and descents.
