I don't see a requirement for FSM's in any of those.  ATM's (I assume
you mean cash dispensers) just seem like they'd run normal business
code.  Cruise control sounds like a normal PID-like controller.  I've
written tons of comms code without FSM's.  On the other hand, maybe your
comm protocol involves checksums or error correcting codes.  Doing those
with FSMs would be straightforward in theory but ridiculous in practice.
