I cannot help but think that there are more than a few hypocrites posting on this thread. Can all of you out there put your hands on your hearts and swear that you have never done 40 mph in an urban 30 mph limit? Personally, I doubt if any of you could.
How many hundreds of pedestrians get killed every year because of this? How many passengers have been killed or injured by Ryanair crews taxiing at 30 or even 35 knots?
I am personally not prone to fast taxiing but I have little doubt that I have probably exceeded 30 knots on a long unobstructed taxiway somewhere in the world on more than one occasion and I'll bet a lot of you out there have too. If I had considered it in any way dangerous, I would not have done it!
