It appears that a lot of pilots are violating airspace even with GPS on

Actually, from what I've read, *more* violations occur with GPS on board than
without. The reason is that pilots with GPS tend to cut pretty close to the
limits because the *think* they know exactly where those airspace limits are.
Pilots without GPS receivers tend to give protected airspace a little more
leeway because they aren't exactly sure where they are.
