It seems that you have very strong interests on the software side, which
need to be considered separately, but here you are really distorting
actual reality. As this example is likely best known to everybody, I'll
comment on this one - it seems currently too much work without a
prospect of any gain to comment on everything.
Of course you can modify your own car. This is *not* forbidden - why do
you claim such a thing? Heck you can even attach a rocket to it *as
long* as you don't use the car on public streets. If you do, all you
got to do is to get your modifications approved. No big deal, go to a
<insert favorite car brand here> meeting and look at the cars there.
I can even build my own car from scratch and get it certified.
Although I wanted to restrict myself to cars - it's the same with
planes. It is common practice for example to modify glider planes
(increasing wing span for example to be more competitive today) for
which the manufacturer even *does not exist* any more today. Admittedly
this is some work to get it certified, but it is doable by a private
person for sure, I personally know some.
Actually I can even build my own *plane* and still get it certified
(this is not uncommon).
Cheers
Detlev
