I got paid Strava so I could create and see how I do on my own private segments over time, after the ride. During the ride if I'm going that hard, it's just a glance at the gps for power or HR. Not watching. When I saw a live segment come up (I had it off, but somehow it came up due to being a 'starred' segment), I did not care for the eyes off the road bit.
I could see somebody watching the +/- figure and slamming into a parked car.
