But the kid taking his driving licence in a Bentley isn't going to use that as a basis for getting an HGV licence? Not entirely comparable.
However, I took my driving test in a Mini Metro (after a bike licence) and bought an Audi Quattro Turbo.
The difference is whether one is going to fly for pleasure entirely or fly as a career. If one flies for a career, then one has to be pragmatic and think about the best career options. Personally, if I can get through a helicopter aviating career without ever flying anything that requires carb heat, then I'll be happy but I also concede that that may not be possible!
