Surprise Cycling: Mapping

Sometimes when mapping a route the mapping software will choose to go
beyond the point you have selected, then track back... the notes will
then instruct you to go beyond that point, turn around and go back
making what might have once been intended to be a Left turn, now a
Right turn - this is obviously a bug... i'm typing this to encourage
everyone to go through the notes while you are mapping you're route
(you can click "undo" and choose a different point in the same area
that does not activate this bug) as to avoid confusion, or getting lost
(like I did)
