> The average car in the netherlands is driven about 8000 miles a year.
Could be (I don't know) because all the people living next to bike lanes and with good public transport have given up their cars, so the only car users left are the ones who really need to drive a lot, raising the average.
It's the opposite actually. Car ownership in the netherlands is actually rather high because it's a relatively rich country where people can easily afford to own a car for the occasional convenience.
The fact that there's great public transport there makes it so that those cars don't get driven as much for day-to-day errands as cars do in other places, so they have overall less driving. 8000 miles a year is relatively low.
