Digger, that basic scenario is how I had my first fall and slide in the road in 30 years (last year) (maybe 5mph).
Taking your eyes off the things ahead of you for even 1-2 seconds can make the difference.
That is GREAT advice!
Although WE don't always heed it, even when we know better.
Yesterday, I was leading a group ride @ Inzane.
We were on I-64 headed back to Ground Zero, there were some dark clouds looming in the sky and they had diverted my attention from the road for a few seconds.
When I looked back at the road there was a large doe standing in the middle of my lane staring at me.
At 75 mph I was closing fast and only had seconds to react.
I grabbed a handful of brake and swerved into the left lane behind her.
The whole time I'm doing my best to "will" her NOT to run in the direction that she had came from.
She didn't and everything was fine, thank God!
Back at the hotel several in the group commented about the incident and asked if I had seen her two fawns standing on the left shoulder?
I hadn't, my complete attention was focused on her, if she had ran back to her fawns it would've been "Game Over".
This just goes to show how quickly things can change and how even a moment's diversion of our attention from the road can become a real problem.
