I don't disagree, but I do wish there was a more formalized way to educate both bikers and drivers on the laws. I just saw the Washington DC official bike map has the laws on it, but others do not. And what use are the laws if the drivers don't know them? Both bikers and drivers need to know them to be successful.

I've asked a good number of both bikers and drivers in my area and they don't know that the laws exist:

A driver must move over to the next lane if it is open and a biker is in the bike lane or the lane the driver is in.

A driver must not pass closer than 3 feet from a biker

A biker may take an entire lane and ride two wide

I think if drivers knew that the above rules, and it became a norm to take the entire lane when 3 feet was impossible based on the size of the lane, then biking would be safer.

To not leave this as a "this is bad" without proposing how to fix it... the education could be incorporated into gaining your drivers license, city sponsored advertisements, or having police actively spend a period of time enforcing the above laws (warnings would be fine, more for education than penalty)... or all 3.
