Not that easy and where did you get 30km from? Most city drivers complain...
Maybe from the Census which has figures for average daily commute.
I think drivers commuting to and from work complain about commute time. Not necessarily the distance per se.
Figures wouldn't include other trips for sport, leisure and etc.

At a national level, people who travelled to work by train had the longest average commuting distance (22.5 km),
followed by truck (18.0 km) and driver of a car (17.0 km).
Generally those who took active transport (those who walked or rode a bicycle to work) commuted the shortest distances.
People who walked to work travelled an average distance of 6.1 km, while bicycle commuters had only a slightly longer average commuting distance (7.6 km).
