I don't know, anecdotally, all my friends (besides me, if I count as a friend of mine) drive automatic.
> and you can’t get a driver’s license if you don’t know how to drive one.
This is definitely not true in a bunch of countries, where you get to chose if to take a license for manual or automatic, where if you chose manual you can drive both and if you chose automatic, you obviously only get to drive automatic ones.
Just now I went to Avis.com set pick up in Rome tomorrow, drop off in Rome the day after, and it said there are 6 types of cars available, and 5 of those types have manual transmissions.
Florence was incredibly calm, respectful and considerate driving. The Motorways everyone was doing just under the speed limit.
My italian friends said that its not the case in the north.
For the ones that do, I would guess they have more leniency than 5%, but I don't know.
I don't have any numbers regarding sales, but after renting 10s of cars in Europe during the last decade, it seems like they almost never have any manual cars anymore. In some countries, the entire fleet doesn't even include any manual ones anymore, I was told the last time I wanted to rent a car.
