Of course the above statement is correct, (bolding mine) but most experienced cyclists have found that lane position does in fact influence drivers, and usually for the better. Even if a driver does decide to pass too closely when you are taking the lane, at least you have some buffer to your right to glide into. Not so if you are on the fog line with little or no shoulder.

Up until this point most of the discussion has focused on motorists overtaking cyclists. But using the full lane offers several other benefits to cyclist safety. Sight lines are much improved when you ride in the lane. You will often be able to see drivers sooner (and they you) than you would when you hide yourself away in the gutter. (think intersections and driveways, but it doesn't end there)

Dangerous infringements on your right of way (like left crosses or pull outs) are also less likely when you are positioned where traffic normally drives, instead of off to the side where people normally wait for right of way.

+1 on taking the LAB traffic 101 course. Pedal On!
