I generally do for these reasons.
They're placed where they are as a guide line for cages, which don't acclerate nearly as quickly and are a lot bigger than a bike.
They make no sense on their location.
2 instances spring to mind. Hwy 97 between Peachland and Summerland, heading south. There's a few examples on this road of where the guy in his truck that was painting them was either asleep or drunk. Double solids but you can see up the road for at least 1 km. The Trout Creek area is a prime example. Coincidentally, the staight stretch around Trout Creek is a popular tax revenue generator.
Hwy 20 heading towards Winthrop. Same as above.
There's spots on this road in the canyon sections, where if your eyes are focused on where they're supposed to be, the road ahead, you can pick out if there's any oncoming traffic as you travel from one corner to another.
I'm sure the Squeemish hwy is like this too, but I try to avoid that "tax revenue road" .
The same goes for the reverse. I've seen broken lines, indicating you can pass at the base of a hill For this reason, if I'm ever charged with passing on a solid, I'll be taking multiple pictures of poorly placed centre lines and presenting them in court.
