Charlie Gibbs is right, while computers running open source software are
under your control, embedded devices are much more restrictive. This is
especially true for automobiles that have absolutely zero documentation
and everything must be reverse engineered from scratch. This also
applies to smartphones whose bootloader is locked with no way to unlock
it or routers/modems.

Even then, most of the population is unfortunately running some sort of
proprietary operating system like Windows or OS X.

No security is perfect, workarounds and exploits will be found but it
might get to the point where such bypasses are more trouble than they're
worth.
