Do you live 150km away from your office? A super commuter commutes >50 miles one way, that's a little over half of 90 miles (which is 150km). Again, the point is what matters isn't peak power or rate of any quantity but the integral, the total. Most of the time commuting is spent moving much slower than 60mph.
In Denmark, the limit is 50kmh inside the city, 80kmh on normal roads outside the city, and 110-130 kmh (68-80 mph) on the motorway, which is where a lot of people drive most of the commuting distances. So the average speed is likely not going to be at least 60 or higher.
No, I'm about 60km one direction - I live rural and work in a nearby city. Each direction is still only 40 minutes or so, so it's not as onerous as it might sound.
