Just saw this on 'Beyond Tomorrow' It's a helmet with rear view vision. http://www.reevu.com/ http://www.reevu.com/what_you_see.asp It looks pretty good, I understand rear view on bikes is usually pretty crap, this may be the answer, no idea how much it costs or the like, will be going through this site with great interest. What do you guys think? is it a goer? or a gimmick?
