7 miles each way - takes about 10 minutes.
I could probably do 30 miles each way if it was 60 MPH country roads with no traffic, but 30-40 miles in the city would be a no-go (like going from Fort Worth to Dallas). That takes close to an hour during common commute times.
I mean, I spend about 20 minutes in the car each day. It would take a lot for me to bump that up to two hours a day.
