I've been wearing a 3/4 helmet since I started riding again a couple months or so back. Well the weather has changed so I went to the winter hat which is a Bell full face. Now I catch myself going way to fast. It seems I got so used to the sound and feel that now the full face has changed my perception of things. If I open the shield I slow right down. I've always depended on the seat of my pants whether riding, driving, flying, or anything else I do but I'm having trouble adjusting to the difference in sound and air movement in this case. Yep I know I'm strange, but surely I'm not totally alone here am I?
