The better question is how many remember driving a car from the 60's that had single speed wipers, much less two speed and much more less intermittent? I know one person in this thread knows first hand.
The even better question is...how many remember driving a vehicle that had single speed wipers w/a vacuum wiper motor?
Vacuum operated wipers work OK when driving on the flats or downhill, but when climbing a hill, the vacuum wipers slow down to a crawl, some even quit working.
This reminds me of when I got my first classic truck and I thought it didn't have high beams because the column turn signal wouldn't push forward for brights. My parents had a good laugh at my expense informing me of the high beam button. What made it worse was that I was 31 years old at the time.

Oh do I remember those days, especially driving in these mountains on a rainy day, procedure would be to apply the gas until no longer able to see then let up and allow the wiper to make a couple of sweeps then apply the gas, this process would continue until reaching the top; however, they did not work much better going down hill, no coasting.
Originally had a single speed wiper in the 65 and swapped for 2 speed and seem to recall it was an easy swap.
