This concept of control is a _very_ irrational one. Of course you steer and pedal your bike by yourself. But by taking part in traffic you give up at least as much control as flying by plane. Some guy hitting you with his car from behind is not exactly in your control.
When I was getting my pilot's license, I learned to be hyper-aware of another airplane that was less than say 1000 feet from me. But the strangest part of those lessons was getting back into my car afterward and getting onto the 417, where I was a couple of feet away from other cars, also going 75mph. I was completely at these other drivers' mercy: I had effectively no time to react to them, and knew from experience that lots of drivers are just plain awful (and this was really before you'd see people driving while texting with one hand and changing their kids' DVD in the other.)
It was very, very scary. Total loss of control — far more than in an airplane, where to a much greater degree if things go sideways, it was probably your fault anyway.
The other interesting thing about the scary drive was how long it stayed scary: maybe ten minutes, tops. After that — business as usual. Didn't even think about it.
It is irrational but it shows how our mind work(what is sometime is irrational and does not always work according to statistics). On the bike you feel like you have more control because you can control one factor is yourself directing the bike and possibility avoid the accident(in your mind). On the plane you have no control in any directions. No matter what happens you are helpless and bets you can do is pray
