. If I did not coordinate with the tower and ran you into their airspace then thats my problem not yours as a pilot.
By the same token, I would expect a pilot to have enough situational awareness to know where he is in relation to airspace at all times, and not allow himself to be run into it without at least querying ATC. ATC provides great service, but that does not alleviate the responsibility of the pilot to know where his plane is going. FAR too many pilots think getting radar service, now becomes "I can sit fat/dumb/happy time."
