Well , when the path is straight there is no major problem even gps
not necessary :P, I was thinking more in offroad tracks that sometimes
 are all but straight ;)
In fact my support frame is rotate able, but if looking at the screen
on the go is not secure, biking with one hand, with the other trying
to follow the direction while looking at the screen on a offroad
track... well at least suicidal.the supporting frame   is a prototype
i will try to commercialize,   but as you can understand is a little
bit more complicated than a leather case :) I hope I can move forward
on this and report good news soon.

And thas the reason is useful to know , in case of doubt , where is
the right path without  following  on the screen what direction your
are moving before stop, just stop, a quick look on the screen and you
know if have the follow the right or the left path in a crossover,
without guessing if the left/right path on the screen is the same as
yours :P

Yes is the right way when your are moving sure!

Totally agree :)
