Something I've not seen referred to here is the very high probability of getting shouted at as a low time PPL flying in UK. I'd say that a single event of this type chokes off quite a lot of new PPL's who never come back as a direct result. My evidence is as follows:
a) It's perfectly possible as a high time PPL in UK to get shouted at, so heaven help the low timers!
b) Shouting at PPL's is a UK national trait that can be seen and heard clearly, not just at airfields, but on the radio and on this and other forums***.
My personal solution to this negative mentality, the high costs and the suffocating bureaucracy was to start flying in the States once I had a PPL and about 60 Hrs. Without this, I would probably have given up as well. With it, I had no trouble keeping current each year in an environment that was hassle free, exciting and capable of limitless reward. That's why I still do it, more than 30 yrs later.
*** by "shouting at" I'm referring to all the kinds of intimidation that is dished out to PPL's by instructors, ATC, FISO's and various assorted airfield hangers on, all too often in front of the poor sop's passengers. Just look at the endless cases of 'infringements' every month in the UK where the pilot should have been helped by a flight following service, not reported to the authorities.
