[Spiderman]

I tried one on at a show a few years back just to see what the big deal was. A good idea let down by the reality of riding a bike imho.

Problem with it was that unlike in a car where the rear mirror is fixed no matter what position your head is in, this system by its very nature means the mirror is always moving.

meaning that if you need to take a long look at something ehind you for whatever reason, then you really need to keep your head pretty damn still to do it.
In a car for example you culd turn your head to look over your shoulder slightly and then just glance back at your rear view quickly. You cant with this lid.

And after a min of walking round the show i found the mirror being constantly "on" beacame a bit distracting as ther was no way to swith it "off". I can ignore my side mirrors for bloody ages if i wish to but not this cos its just above your line of sight.

Got a thumbs down from me.
