Good answer QDM.
Mate of mine used to commute by microlight - but then he did work on the airfield! He only did it during the week when the traffic was bad because that was the time flying was quicker (not just flight time to count but getting togged up, getting a/c out, driving to airfield etc etc).
Personally, I've always wanted a paramotor so I can get to work by air from my back garden. Flying everywhere is the future!
