I grew up, and learned to drive, in the UK. My kids learned to drive in the USA, so I can speak about the differences. In New Jersey, everybody takes the driving test in an automatic, on flat ground, away from any traffic. It's a wholly inadequate test of driving ability.
If someone learns to drive a manual, it's probably after they passed the driving test and the instructor is a friend or relative.
I taught my son to use the handbrake on hill starts. My wife is German and she doesn't use the handbrake for hill starts, just footwork. I guess it's a cultural thing.
Another funny difference: I taught my daughter to do the push-pull steering technique, with the aid of a dinner plate. Her driving instructor told her she'd fail the test if she did it that way. And if she used the steering technique her driving instructor taught, she'd fail the driving test in the UK.
And while I'm on the subject of cultural differences in driving, I have other British driving habits that don't translate. For example, I check my mirrors before signalling. My wife believes this is completely wrong, and you signal first and then figure out what is going on around you. In New Jersey using the signals is regarded as a sign of weakness. I'll also adjust my speed to let another car merge safely. This often just causes confusion because the other driver doesn't expect me to let them out. For safety's sake I have to become more ruthless
