Oh cool, I'd missed the location. I've ridden that stretch of road many times. The speed might be realistic, I may or may not have been on that very stretch of road a few days ago in the SUV with the kiddos and my dad, and I may or may not have been doing just a hair under 100 and just going with the flow of traffic...
The speed limit is 70, most of the time people are doing 80+ there, and it's not uncommon to get with a group doing closer to 100, and that's just regular drivers not a zip-splat super sport bike.
However, I hope he had good brakes, 'cause there's a good curve coming up just ahead of there!
