I think in real world in the USA it's like 20knots unless stated otherwise, but I saw Keith taxi faster than that on at least one of the instructional videos.
I'd think that the common sense rule on PE would be that it doesn't matter as long as there's noone else taxiing at the same airport at the same time, and as long as I don't take off while taxiing. After all it's a safety rule, and it will make no difference to the controllers if I take my sweet time or if I get to the runway very quickly. But then again, if I taxi with 40 knots it's unrealistic, and we're trying to simulate reality here.
The reason why I'm asking is that taxiing is the only boring part of the flight and I was wondering if I can shorten that time a bit ...
