Had a pretty bad experience on Pinehurst today when I went up for a lunchtime drive around 1pm. I was stuck behind a early 2000s Toyota Camry that kept going over the middle double yellow lane lines frequently, including in the blind corners. I was stuck behind them for 10 mins or so and I couldn't figure out why they kept doing this, and I was getting increasingly worried through the blind corner sections, hoping that nobody was coming in the opposite direction.
Surprisingly, they pulled over to let me pass and I actually stopped alongside them and motioned for them to roll down their window. It was some mom with her daughter I guess. I told them "Please don't drive over the middle lane lines on this road." and she just said something like "Oh" and began nodding slowly. So I said again "DO NOT cross over the double yellow lines" and she just kept vacantly nodding - maybe she didn't understand English? So I finally just said "Please don't cross the lines, that's how motorcyclists get killed on this road." which is a completely true statement.
I got ahead of them and then stopped at the intersection of Pinehurst and Redwood and got out so I could take down their plate and call it in to CHP. They rolled up and the girl in the passenger seat was aggressively yelling things at me out of her window.
Anyway, turns out CHP can't do anything unless you call 911 while it's happening and they get an officer out to see it happening. And calling 911 on Pinehurst might prove difficult considering there's no CELL SERVICE up there!
Careful out there guys, would've hated to see a fellow twin, cyclist, or motorcyclist coming around one of those blind corners directly into this person's front left bumper.
