Here is what you actually want to do. At that inflection point you should be riding the bumper of the person in front of you with the fastest and most consistent speed possible. If you are doing that you won't have focus to spare to turn your head to the side. That's what maximizes the speed of traffic at the bottleneck. It's the only point that actually matters so it's just 2 seconds of real focus. If everyone did that we'd be flying past these accidents.
