Re: turning right...why does it seem harder??
I might guess that our experience on the road makes us more wary of the right side (in the U.S.) because when you turn right in normal traffic, there are things much closer to your right side (lampposts, waiting pedestrians, etc.) than on the left. The way to check if this is true would be to see if riders in Britain/Australia/Japan are more wary of left turns in general.
