I don't think there's much difference to learning them.
It's true that learning Manual is a little steeper but by the 6th
hour, or 4th-5th lesson, it's mostly muscle memory. So there's not
much gain in learning Auto.
Unless your left leg is retarded... And you suffer from Psycho
motor problems... then maybe you want to take Auto, or perhaps, dun
even learn at all...
I mean the essence of learning is not how to manipulate the car
only. To do that, you don't need more to clock more than 10 hours
to be proficient at the mechanics. Learning how to drive is more
about safety and traffic rules.
