We call it “DWA” around Silicon Valley. This past weekend, a DWA-F pulled into the bike lane ahead of me and proceeded to drive in it for a hundred yards at 10 mph. Being extremely wary, I dropped back a bit. Good thing I did because she cut a U-turn right in front of me without looking at all. A very common occurrence here in Silicon Valley. No peripheral vision and, even worse, no head-turns.
Gee, on Saturday in San Mateo I had one of those in a beat-up Honda sedan make a right turn from the leftmost of two left turn lanes. No signal or head movement - the fact that she was sitting there on a green left arrow made me wary tho so I slowed down...she turned right to pass directly in front of the police station - then turned into the side street and before stopping again and turning right again back onto the original street (at a "no turns" sign).
Today one of the young ladies at work was involved in a "following too closely" fender bender...we all nodded our heads knowingly. The other day I found her trying to park next to me and failing miserably. After a few too many attempts I told her to move over and parked it for her. Apparently she never drove when growing up in India, and didn't start here in California until she graduated from college. I can't quite comprehend how she passed the driving test.
