"Think of bicycles as rideable art that can just about save the world". ~Grant Petersen
Cyclists fare best when they recognize that there are times when acting vehicularly is not the best practice, and are flexible enough to do what is necessary as the situation warrants.--Me
For the cyclists in that video, I agree that the only way to keep them safe would be to remove them from the roads completely.
I think the best lanes shown there were the ones with the poles spaced about 4 feet apart give or take. Prevents cars from using the bike lane but allows the cyclists easy access in and out of the lane. The one with the slightly raised bump is not bad but could cause some problems for entry and exit.
