Vacuum wipers. Argh, who dreamed up those things? Climbing a ten mile grade at night in coast mountain rain, having to back off the gas every few seconds so the wipers would give a swipe and you could see where you were going for a few more seconds. Terrible things. The only thing good about them was the vacuum hoses were great for synchronizing the SU carbs on my Mini Coopers.
Yes, vacuum wipers left a lot to be desired. But think about what they replaced. If the windshield got wiped it was hand powered.
And with 6V generator that did not put out much at lower engine speeds electric wipers could of killed the engine.
