Since one could theoretically create another class that supports
#start (and your later examples of #gear_up and #stop, probably
delegating #gear_up to a Transmission-like class), I think it's still
effectively decoupled. In particular, when *testing* the Car, one
could create it with a MockEngine that's only used in the tests.
