And we know that's probably false. During rush hour in a real situation, you probably would have more cars than in another rush hour. And if you wanted to be more realistic, maybe we do it in a day. Because in a day, any period of time, actually, no, I shouldn't do a day. We have to assume that every hour is completely just like any other hour. And actually, even within the hour, there's really no differentiation from one second to the other in terms of the probabilities that a car arrives. So that's a little bit of a simplifying assumption that might not truly apply to traffic, but I think we can make that assumption.
