I talked about this recently on my blog (
https://velonut.com/blog/bicycling-d...orida-cyclists). The short version of my opinion is this: We weren't there so it's hard to say exactly what happened. I do know it happened on a road with a 55 mph speed limit and she was doing close to 65 mph. She admits she was speeding. She admits to looking down for a second. On a road like that, that's all it takes to miss a group of cyclists, a pedestrian, or anything else. There's details we don't know such as "was there a bend in the road?" I think we have to give everyone the benefit of the doubt. Plus, I don't believe every driver should be punished with the equivalent of a felony offense. No need to completely ruin a person's life over what is truly an accident. Again, we just don't know enough to truly judge.
I do wonder this though: What the heck was that cycling group doing on a 55 mph street? I've ridden with many groups and we simply avoid high-speed streets for that very reason. Just way too easy for accidents to happen.
