Yes. I got my first job (in 1983) in Great Baddow, and decided that the best way to get there was by bike. This was how I got into cycling: I bought my first adult bike for the commute and discovered how much I enjoyed riding it. Though the commute itself wasn't much fun as it involved croosing the Army and Navy roundabout (this was before the Chelmsford bypass), and before long I moved out to Maldon which, whilst a longer ride, was much more pleasant.
I continued to cycle commute through various jobs after that until 2010, when I got a job which was too far from home to make cycling all the way practicable. So whilst I could go all the way by train, I've generally cycled to a station a bit further up the line and caught the train from there.
As I was commuting between towns there would be at most one rider going the same way.
I worried about theft after my first bike was stolen (not from work, though, that was secure). Not had one stolen since. Distracted drivers were more of an issue, as I was hit a few times on the Essex commutes, though only badly hurt once.
I never bothered to log mileage, though the longest commute was a round trip of 35 miles (Maldon - Colchester).
