Could it be that they seem superior to you because you are British but that the writers intended for it to sound mixed at best?The Two Georges is a guilty pleasure of mine (LTTW can arguably be considered my attempt to do 'continuing British America' more realistically) because it is so relentlessly anti-American in tone. Not only does the OTL USA compare unfavourably to the NAU in matters like racism, but we never see downsides from the lower level of technology (like someone being killed by an illness treatable in OTL). About the only exception may be the description of miners/the class system in Charleroi. British terminology and culture is shown to be universal and dominant: trucks are lorries, people wear cricket caps, etc. Never mind that this didn't actually happen in the OTL British Empire where Australia, Canada etc. all have their own distinct terminology and culture.
