I’ve always found even the strongest Texas or Arkansas accents intelligible, unlike some regional UK accents. The US used to be more varied but being one national market for media and immigration has had a homogenizing influence. It’s not simply a question of age, some parts of the US are 500 years old, and in some ways it’s British English that has drifted, not the other way round.
