That's about half of it... but at least as far as ultralights (powered
paragliders in this case) are concerned, the FAA interpreted a busy 4
lane highway with clear fields on each side a "congested area"
(ultralights have NO minimum altitude, but can't fly over a "congested
area" at ANY altitude).

Are you even allowed to *cross* the highway? If not, that could put a
serious crimp in your travel plans, depending on where you're flying.

I see the interpretation as not only "can you
land safely", but also "if anything falls off the machine will it be
likely to injure anybody on the ground?"

Not to mention if the machine iself falls from the sky.
