This is the kind of half-correct pithy quote which falls down at the edge cases, e.g. if you're writing an algorithm that selects the lowest-speed car for new learner drivers and for some reason a blissfully unaware learner ends up in a McLaren GT with no brakes for lesson number 1.
How fast would you drive a car if I gave you the keys and told you „everything works perfectly fine, however the brakes have been removed“?
