The 12 lessons before the test is just a money racket as well.
This is how I learned to drive, bought a car, got insured on it, then drove on the roads with my dad for 1 hour on a saturday, it didnt even go that well.
on the Monday after, I went off driving by myself and the rest is history. I didnt get proper driving lesson for 1 year + after that day driving with my dad.
Now looking back on that, it wasn't right but 12 lessons isn't needed. and what is the max speed someone learning to drive will reach in a lesson? it was 30 mph when I was getting lessons which is crazy.
