It's hard to breathe and the sweat running into my eyes would burn and really make it hard to focus. It's personal choice that is going to vary person to person and should not be mandatory for all riders IMO.
Most people who use the "if I have to wear a seatbelt you should have to wear a helmet" argument are not riders themselves and opinion has no place in the topic.
