Bike paths are great.
Steets are great.
Where bike paths meet streets... anything but great...
This thread is about yet another example of why.
Yes, motorists should be more careful, but, bottom line, motorists are primarily concerned with other vehicular traffic. That's where their focus us, that's their biggest threat, and that's what their mostly aware of. Of course, the amount of focus and awareness varies from driver to driver, but the point is that at a bike path/crosswalk crossing of a street, some probably-higher-than-most-cyclists-would-like-to-think-about percentage of motorists are simply not paying attention to the crosswalk. You can argue "but they should" all the way to the grave, but that's not going to change. Human nature is human nature. That which directly threatens the motorist... another motor vehicle... is going to be their priority. That's primal. And some only have enough band width for one priority...
Bike path crossings of streets can be extremely dangerous, and should be treated by the cyclist accordingly. Did you have the legal right-of-way? Of course. Should you have been more careful, perhaps walking the bike and only when you knew it was clear without assuming you were seen? Only if you want to avoid this type of collision...
