British and americans same now in most ways?

There still are differences like with driving on the left side of the road, fish n chip shops, the sun newspaper, etc. I guess I was referring mostly to modern character and attitude similarities between the Americans and British.

For a start England was the birthplace of the Imperial system. They went metric to match the rest of the world. The Imperial system is so clumsy with 5280 feet to the mile and so forth. The metric system is decimal based so a kilometer is one thousand metres. A Metre is about 39 inches.

Doing a little research I have found the reason for driving on the right is due mainly from the mule trains used in early settlement days. The mule skinner (driver) would sit on the left rear mule to leave his right arm free to snap the whip to encourage the animals to pull. If another mule train was coming toward him he would stay to the right to be sure his wagon wheels would not get caught on the other wagons wheels. When cars were started to be produced everyone followed along with driving on the right. The first cars produced had tillers instead of steering wheels but when cars started using steering wheels the wheel was on the left so the driver could easily avoid vehicles coming the other way the same way the mule trains did. Google is such a wonderful tool. :)

Oh I know most English still love tea. It's, as you said, the stereotype to assume they are still like the stuffy butler stereotype speaking the queen's English. Maybe still with the elderly generation, and even then it's only the more affluent. Elderly Cockneys still fit the Oliver! stereotype, sort of, with "fucking" added to every sentence. They've all picked up the younger more modern Brits' habits of cursing their asses off. Northern Brits, there's nothing old fashioned about them in any of their ages. Old fashioned Britannia is almost extinct.
