I drove down San Jose last Friday for the first time in forever and, "Wow!".
From the car, those lanes looked as though they were 6-7' wide. The part that irks me is that the space for the lanes has been there since forever, what's the 'dragging of the feet' for just adding a simple stripe to the side? It shouldn't take a $4M resurfacing project to add $10k worth of paint - on San Joes or any other road that would be used more by cyclists.
On a kind of WTF moment on my way home, there were two asshats on tri-bikes (assumed due to the aerobars) that weren't content with their new bike lanes and were still a couple of feet into the traffic lane. I guess someone's gotta be 'that guy'.
