The cars may be surprised to hear that I try and time this so that they do not miss their "I'm going straight!" green light. I do though. Happy cars are cars who are good to bicyclists and I make a concerted effort not to get on their bad side.
On this instance though, I hesitated too long as I tried to figure out of an approaching Jeep actually saw me and was actually yielding. It was. We both arrived at red lights. His for going straight and mine for taking a left. I felt bad about this.
I glanced over my shoulder to see if the driver looked angry and I saw that the window of the Jeep was down and the driver was just kindof sitting there nodding along to the music. On impulse I said "I'm sorry about your missing the light."
He looked over surprised and then laughed and said "No worries. It's a beautiful day and I'm in no hurry."
Biking in the bay area can be Quite Nice.
