Anecdata: A lot of people I know take about 20m (suburb to a major city) or about 30m (rural countryside), one way. My dad drives ~1h because in the country side he doesn't find a job in his area of expertise (now that we kids have left, they think about selling the house and moving to a better location).

Better data: https://de.statista.com/infografik/13644/laenge-von-arbeitsw... Can't find how to change the language, even though it's an international page. The graph shows minutes per single way. The pie diagram seems to be a popular vote on "maximum acceptable time".
