anyone who has ever driven a car can tell you that it's easier to join a flow of traffic at 20mph compared to 30mph.
apart from anything else at the more relaxed pace of 20mph I've noticed that people drive a lot more politely and are more likely to let people out.

by your logic should we increase the road speeds to 50 to help nervous drivers pull out of junctions?
