Well the math is all wrong anyway. There may very well be 36,000 cars on the road, but the driver isn't passing that many. I bet the driver only passes at most a couple hundred. The traffic flows together, roughly. You've all been sitting in traffic and seen a car in another lane pass you only to have you pass them 30 seconds later once your lane starts to move. You play tag that way for most of the traffic jam, which means you have been averaging the same speed all along.

I was thinking this too. And the only people he'd be flipping off are the ones who cut him off, not people he was passing. Who just drives past people flipping them all off?

It sounds like Glatt, classicman, and I feel fairly safe in flipping off people who cut us off in traffic, although I live in Los Angeles, so the odds are greater I'll be killed. You can get shot out here for using your horn when people cut you off. They think if their car will physically fit between you and the car in front of you, it means you're letting them in. They have no clue what "safe following distance" means.

True, if the traffic is jammed up and inching along, but if the traffic is heavy but flowing, with the lanes at different speeds, in 96 miles he could be passing that many cars.

Only if his lane is free flowing and the other lane is filled bumper to bumper with stopped cars. For 96 miles.

36,000 cars times 14 feet for the average car length is 504,000 feet or 95.45 miles.

I've never seen driving conditions like that.

Yeah, well he says,

Most of the bumper-to-bumper is on an 8 lane highway. There are 7 cars every 40 feet for 32 miles. That works out to be 982 cars every mile, or 31,424 cars.
You can't fit 7 cars in 40 feet therefore he must be talking about the 7 lanes other than the one he's in, so he's counting the cars going the other way, I guess. I wouldn't call a car every 40 feet bumper to bumper. Also 40 into 5280 = 132 x 7 = 924, not 982. And 924 x 32 = 29,568 not 31,424, add the 4,000 on the other 64 miles of road and you get not 36,000 but a measly 33,568.

Say, you don't suppose he was exaggerating because it was a joke?

I was waiting for someone to state the obvious.
