I’m going to pretend to avoid asking what is a mile and what is 250 and 500 :)

I could imagine ways we could interpret “500 miles” the same way as The Proclaimers i.e. as a noteworthy or arduous distance, under which that claim “it’s 500 miles from Dallas to Houston” isn’t contextually false.

More interesting is what knowing that things are not the case tells us about what we can know is the case. I don’t think it reveals much, but I’m not sure
