Bobert, you said "We know what Einstein had to say about insanity: repeating behavior and expecting different results..."

Of course he didn't have to deal with Microsoft.

Engineers routinely design structures to survive a fifty year gale. Most modern structures have a prospective life of around thirty years.

Americans are too stupid to use traffic circles (roundabouts). They've been succesfully used for many decades in the UK.

Then there are those traffic lights designed to cause accidents. You arrive at the light and want to turn left, and there's this left filter sign that works SOMETIMES. So for nine times you arrive at the light and turn left when the light changes, the tenth time (or thereabouts) the filter sign doesn't come on so you start out as you have been conditioned to do by observation of the previous behaviour of the signal, anticipating a little of course. Now you're out in the intersection with oncoming traffic bearing down on you.

Then there's those filter signals which only work if you have a heavy car. it doesn't see a small car at all so your only choice is to run the signal, 'cos it's ALWAYS RED.
