In the past drivers were taught to keep their hands at 10 o’clock and 2 o’clock. Now it is advised to hold the steering wheel differently depending on your steering technique
Hand-to-Hand Steering: When using this method, your left hand grasps the wheel between 7 and 8 o’clock, and your right hand between 4 and 5 o’clock.
these changes were caused by the inclusion of airbags and steering wheels becoming smaller
it is also advised to not wrap your thumb around the steering wheel but instead keep it flush to the face of the steering wheel, because if you are in an accident and the air bag is deployed your thumb being wrapped can cause injury

Meanwhile I’m here avoiding airbag related injuries by driving cars old enough not to have any. True big brain move right there if I do say so myself.
They’re also easily disconnected in case you don’t want to be in a statistic like:
My wife (a ‘smaller woman’) will not sit behind one.
