@gtwilson Yes, just my daily commute works out to about 482 km also. I drive an average of 20,000-25,000 miles a year (roughly 32,000-40,000 km), and that's been pretty consistent for the last couple of decades.
As for the biggest engine in a car I've driven, that's probably the 429 cubic inch (7-liter) engine in my grandmother's 1965 Cadillac Coupe de Ville. The car weighed approximately as much as Tower Bridge, so you needed a lot of engine to get it moving.
