I've never seen this dislike before.
Honestly though, even if I had, I couldn't tell someone the distance in km if I wanted to. If I had to guess the distance from my work to my home I'd guess... 25km? *checks* Apparently it's 20km, so not too bad. But I guessed that based on the time that it takes to get here, not the other way around. If someone asked me how far it was I'd just say 30 minutes by car, an hour to an hour and a half by transit.
Frankly, I'm surprised how people actually know the distance irrespective of the time it takes to get there. There's also the fact that multiple routes can be very different distances, but take similar amounts of time. Given that time is really what you care about when it comes to a route (If a route was twice the distance but took half as long you wouldn't take the shorter distance route) I don't understand why you'd give a distance.
