You are wrong.
Say, we define that there's a certain probability of accident associated with a pit-stop. When there's so many cars pitted in a short time frame chances of accident increase. That would not be a problem only if accidents are completely independent, but it is obvious that in this case one accident would INCREASE probability of another. E.g. lost wheel would be less of a problem if there were not so many people working. This is a problem.
When there are so many pit-stops you can have domino-effect in no time.
ironically I think ban on refuelling made matters worse as stops are so swift and people don't have time to react.
