I learned in our old 1933 Chevy with 3 on the floor. No synchro in those days so we had to learn to double clutch. At 6 years old I could barely reach the pedals. Interesting times.YES!!!! That is how I learned to drive.
When I went for my license the driving test had to be with a stick. I couldn't take mine because we had an automatic. I had to make arrangements with my aunt to use her car with a stick. No problem, I'd been driving sticks since I was 6. Passed with flying colors. Still driving sticks and double clutching.
