Inappropriate use of the loud peddle i suspect.
Likely. The key word is "convoy". I used to go out on group rides on my bike but very rarely do so now because men in a group tend to show off or at least try to keep up with each other. The result is what starts as a sensible ride out ends as a semi race.
Plus the performance of cars like the Zonda has got to such heights that its completely unuseable on the roads.
