Can we talk about how many lug nuts are on a semi truck?

I was reading an old shop manual from the 70s at the library in Springfield and it said a standard 18-wheeler has 40 lug nuts per axle. That's 160 total for just the drive axles, not counting the trailer. I had no idea the number was that high, it just seems wild to think about tightening all of those. Has anyone here actually had to do a full re-torque on a set like that?

Trying to count them all is how I failed my driving test the first time.
