> Out here in the real world it’s very obvious that vehicles can’t have half an axle or 4.29 axles.

Yeah, I'm thinking you don't have much exposure to real world trucking and lift axles at all.

It's not uncommon for heavy load truck trailers to have axles that are only dropped to the road to take up a heavy load and are retracted for lighter and no loads to extend the lifetime of tyres and bearings.

Operationally, over their road time, the number of axles in contact with tarmac becomes fractional.

If you're going to make sweeping claims about "the real world" it's best to be across all those pesky actual edge cases.
