So enlighten me on the two most common issues.

(1) Proceeding straight through an intersection. How are the bike lane separators designed so that cyclists are clearly visible to vehicles that are turning right from the cyclists' left? How do vehicles intending to turn right from the cross street, onto the street where the cyclist is, pull up so that they can see the traffic running parallel to the bike lane, without interfering with the cyclists' ability to go straight?
One way to deal with improving the visibility of cyclists stopping at an intersection in a separated bike lane, is to have the roadway markings for stopping the cars, that is slightly staggered behind the first cyclist that stops at the corner.

I'm not confident that just having wider roads is going to get car drivers to pay attention or more respectful. I just don't think car drivers think that widening a road is for cyclists (without a painted bike lane), they tend to think widening a road lane is for them as car drivers and to move more quickly. Let's get real.

Dearie and I were cycling on one of the San Juan Islands and were stunned how wide some the road lanes were....on an island. It made no sense. The traffic was quite moderate. We were cycling in some small towns on a weekday when people were working... a more accurate reflection of regular traffic patterns.
