Cars as old as E30 BMW's ( like late 80's 3-series) have been "get in it and drive". Pretty sure warming up may have come from carb engines. Of course... Hot rodding a cold engine is silly. Co-worked of mine blew his Harley up in our parking lot. Started it up, revved it real hard to show off ( god I hate that shitty 35hp 2 cylinder sound), and it threw a push rod.
