The main issue is that I used to spend the commute reading books. So I have basically exchanged "mental" excericse with physical excercise. I feel that listening to an audiobook while cycling is a bit too dangerous for an urban commute like mine.
I really sympathise with this. I changed job about two yeas ago and switched from an hour long train ride to a 30 minute cycyle. The shorter commute is great, and the in built exercise is great, but man I really miss that chance to read, or just relax.
