It can be more confusing than you think at first, all the N/D/L stuff, some then also have 1/2/3, which "gear" to you start the car in, what to do when you come to a full stop (nothing, doh), ...
The very first time I sat behind one was to drive a family friend home who drunk a bit too much, with his own car... I was a bit overwhelmed
Don't forget the good old mistake of hitting the brake when searching for the clutch pedal (though that only happend to me once as I drove automatic the first time)
Im an american and just visited Germany. I rented a stick, but was given an automatic because they ran out of cars. The rental company asked, "Do you know how to drive automatic?". Just the thought of it kinda blew my mind.
Driving in Germany was a geat experience. I really wish america would adopt alot of the german driving laws and thinking. I would however be sad about the car modification laws.
On a side note, i spent a day of the trip doing laps at the nurburgring in a manual hyundai i30n. Life changing experience.
It was pretty impressive, though i am bummed i didnt get to drive the focus RS. The rental company got rid of it before i was able to get back due to the delays of covid. I would have been more comfortable in the focus as that is my daily.
