And should it be made proper transport?
How could it be?
You'd have to fix the weather first!
Then you'd have to fix the £3/minute hire costs, down to a few pence to compete with the likes of easyJet (so the toy-aircraft-from-farm-strip brigade are still waaaay too expensive).
Then it might be worth worrying about the landing charges.
(I
have used an SEP as "proper transport" in the UK. Twice, in twenty-something years of flying. (And I've failed more than twice, because of weather.) Both times it won only because the north-west quadrant of the M25 is usually a disaster, and because I chose not to care about the cost.)
