When they 'learn to change lanes to pass'. Because they're not doing that now, and won't all learn the same day. Until then bicyclist put their life on the line every time they go out on the road.
Do you have any statistics to back up your assertion that faster traffic does not change lanes to pass a cyclist taking the lane where taking the lane is defined as riding between the center of the lane and left your track? One experiment [1] demonstrated that motorists consistently changed lanes to pass when cyclists rode in the position I described.
I do ride at least 1000 miles a year on roads with traffic speeds ranging from 0 to 50 mph. I've been doing this for over 15 years at this point and my personal experience matches up with the results of that experiment I linked to in my previous comment.
Do you cycle? Do you ride in the primary position that I described earlier by default?
