If I'm going down a relatively new descent, I'll use the bike map computer to visually confirm if there is a sharp turn or other hazard that might be on a blind corner (side roads connecting). I only need to glance at it, but it's very useful.
Yep. Can confirm. Quick glance, tells you what you need to know. Car drivers (sad to admit myself included) take their eyes off the road for much much longer. What I'm saying is that you do look at the bike computer.
