If the situation really was "speeds like everyone else," you're right that it wouldn't be a problem. 5 to 10 mph over is that range, maybe 15 in the right conditions. He posted himself going 96 mph in a 35 mph school zone (155 kph and 56 kph respectively for our metric brethren), which would still be a massive problem even without the school zone part. It's extreme enough to no longer be about one incident but the mindset persisting behind it.
