So Caltrans officials want to add more diamond lanes (June 30). Perfect. I'm sure they've spent millions studying the situation, but apparently failed drive a road like the 10 Freeway, eastbound from downtown, during rush hour. Had they, they would have seen bumper-to-bumper traffic barely moving next to an empty diamond lane, the typical pattern.
Caltrans hasn't figured out, or refuses to admit, that most people's jobs, geography and schedules won't allow them to car-pool. So it refuses to do the one thing it could do to improve traffic flow: open the diamond lanes to regular traffic.
