Ans; 5,280 being an old english mile. Irish mile is over 6,000. Scotish is about 6,000. And the french is about the same as the old english mile. A cars/bike mile is probably standardised (don’t know this one which is probably your Q in the first place). Trucks are usually in Kms but depend on the size of tyre and if new/worn (as their recut after wear) put on after calibration (every two years) to get around limit factoring speed limiters hence trucks passing each other at 2kmph blocking up everywhere (rigerously limited to 56mph).
Cos reality catches up with them and they can’t cope with reality.
What shall I get my man for Christmas? He’s got a bike and is fussy what goes on it, he’s got a car and I don’t know anything about cars, he’s not terribly fussed about music, should I just put on a ribbon and present myself?
