... with the caveat that > 10 and 2 o’clock is no longer recommended because it can be dangerous in vehicles with smaller steering wheels and equipped with airbags. (Source: https://driving-tests.org/beginner-drivers/how-to-hold-a-ste... ) and the implication that otherwise the trad 10 and 2 position recommended for decades is still 100% A-OK.
Not sure about GP - but in my country they teach the 9 and 3 position when you take your license. I’ve always thought 10 and 2 was an American thing.
As far as I am aware, teaching students 10 and 2 has long since been phased out supposedly due to the increase of arm injuries in the event of an accident. 9 and 3 wasn't recommended to us because if your air bag deploys, your right arm will smash into your passenger or the passenger air bag. 8 and 4 is supposed to be safer but it comes with the caveat that you have to steer your car a specific way.
That being said, I prefer 9 and 3 and it's hard to find drivers in America that don't use this position as their default.
