Maybe this is very european of me but 250KM is outrageously far. Dublin to Belfast is like 130KM. If it says they're in Seville (in Spain) within <200KM they could also be in Portugal, Morocco, or Gibraltar. If it says you're in Brussels within <200KM you could also be in France, England, Germany, Netherlands, Lux. If you're in Vienna (Austria), you could also be in Germany, CZ, Slovakia, Hungary, Slovenia or Croatia. Maybe you're in Vilnius? You could also be in Latvia, Poland, Russia or Belarus.
It's short by Australian standards. I was born 1000km away. It's a 12 hour drive. I've done it numerous times. It was a regular thing when I was young.
Uni students have been know to drive for a drink at the pub at the next Uni north (at the time) over the weekend for a lark. That's 2000km, one way.
A serious undertaking by Australian standards is a drive to Perth. That's 5000km in a straight line, but of course you can't drive in a straight line to Perth.
I met a guy once who was the last leg of circumnavigating Australia on his push bike. It had taken him years, and it looked like it. I've never seen someone so wirey, so obviously fit. Yet he rode at a slow measured pace. That was no doubt a habit forced by the trailer his bike towed. I guess the trip was around 15,000km.
Comedically far.
