My wife and I work in the same town, so we go as a family. Drop eldest child off at school, drop youngest child of at nursery. drop wife off at work, then me. Takes 30-40m on a normal morning in our own car. She used to to have a 30 minute motorway commute before a change of job last year, we save a fortune on petrol now.
If it was just me it would take 15m.
