I used to have grand thoughts of doing that but the reality is a little different. For a start during the winter months you like me probably go to work in the dark and come home in the dark. So that is about 5 months of the year gone. If you don't want to get stuck without transport at the wrong end, it has to be flyable in the morning and a forecast of being flyable in the evening. That takes care of probably another 5 months by the time you add all the days together. The take off the times when you may need the car to go somewhere during the day or on the way home, or maybe drop the dog off at the vets or pop into Sainsbury's etc etc and you are probably left with about 30 week days when it really is a possibility.
I have a helicopter at home and a field just up the road at work where I can land and I manage to use it to commute about that number of days in the year.
I long ago decided that sitting in meetings peering out of the window all the time at the gathering clouds was much too stressful to be a realistic long term commuting solution.
