So I started driving lessons in a manual and I want to pass my test in a manual. All is going well. However, my dad started teaching me in an automatic at the side. But in my next driving lesson, it took me longer to get warmed up and used to the manual car. My instructor says that happens if you mix in automatic driving, and I shouldn't drive in an automatic as it'll confuse me and take longer to pass.
Is this true? My dad's car is a bit different (braking, steering, everything) so it makes sense...
