Please note that this is an
international forum, so mph is not familiar to many members. I guess you meant 180mph/290kmh and 140mph/225kmh.....
And I must disagree a bit with your point here.
On one side NFZ's are justified indeed, much more in really near vicinity of airports, and pretty exaggerated at the point that at
1,5miles (2,41km) from A category (large intl) airport we are limited to
35 feet (10,6 meters) !!!!
A plane, be it a jet-liner or a small private 2-seater turboprop, at that height and distance (actually, at any hight below few hundred feet)
is probably seconds from crash landing and/or disaster,
so hitting a small drone on the way to disintegration wouldn't matter anyway..... Although investigators could get off the track as to what cased the incident if they found a 3-axis gimbal pieces inside the remains of pilot's scull....
For those newbies not clear with NFZ walkabouts, here is the visual

As regards to limitations in car industry, think in Europe we have the Autobahn (highway in German, and the name of it) which, in many sections, has no speed limitations. Only recommended speed. You can drive 200mph+ (320kmh+) if you wish, as long as you don't cause an accident or kill someone. If you do, you are f....ed. And funny thing is, there are less accidents there than in many other limited countries.
All other countries in Europe have limitations similar in variety to those in US, ranging from .... ahhh forget it, ....here is the link, check it.....

The point of this? If I live in a country with highest speed limit of 80mph, and I am offered a choice of two cars, one with 80mph max limit, and the other with 130mph, guess which one will I buy....? Yeah, you guess right, the 130mph one. Before you judge me, think of the other guy that bought the 80mph model, a model citizen deprived of free thinking and will, getting pissed of one day by his mother-in-law, driving across the pedestrian crossing just next to the elementary school on busy Monday afternoon at hmm...70-80mph? I know why is what and what can, may or could happen. The other guy....well, maybe he does not.
You made a notion that a mustang buyer may not go over 100mph, but this may be mostly due to lack of driving skills, or feeling unsafe at higher speeds.
Do you believe anyone, literally anyone amongst Phantom users, feels the same fear - flying their bird - at heights a little bit above 35 feet?
The bottom line, where I think in long term limitations WILL affect the sales is the psychological factor of someone/something limiting you. Your freedom of choice
Which is the opposite of basic right of every living thing on this planet - and that is to be free.
Limitations are for primitive societies, but unfortunately, we had, have, and will have some stupid, irresponsible primitives flying at jet-liner approach heights, even more stupid putting videos on youtube etc, who started and are generating this misery for the rest of us....
