My non-riding wife thinks so.

We were riding down a busy road, three fairly congested lanes in each direction. There was a gutter bunny riding with traffic; he was just ambling along on his mountain bike. Cars were squeezing by him in the right lane, coming pretty close. He just kinda took it in stride.

I was in the second lane over, and as we came up to him, I slowed to let a car change lanes and get in front of me to give the rider more room.

My wife, who hasn't ridden since she broke a kneecap in a bike fall in grammar school, looked over at the rider and asked me, "Wouldn't he be safer if he just took up the whole lane and made cars change lanes to pass him?"

I answered, "Yes, dear."
