In Italy we say, if you don't learn how to drive manual transmission cars, then you don't learn how to drive at all. Also if you rent a car on, let's say, a Greek island you go on vacation to, it's likely to have manual transmission, and they won't give it to you if you don't have a license for that

It might be hard for the Americans just like our education system, but trust me, once you've learned, you'll get used to it and won't even notice.
