Like many here, I also learned to drive on a manual trans, three on the tree.
Back in the 80s I had a lady friend who owned an old Bug that needed(?) leaded gas and had a man/auto trans.(I can’t remember what it was called). You had to throw the stick through the gears, but there was no clutch pedal. First time she had me drive it I was doing OK until I pulled a downshift...nearly put us both through the windshield. Muscle memory had taken over and just before I threw the stick my left foot slammed down on the *BRAKE* pedal. LOL
