Meanwhile, in the UK...
They (and the tourists) have apparently never seen limousines before. Jane Kelly of the Evening Standard investigates in Inside London's limos:

Whatever you think about the tackiness of limousines - 35ft emblems of U.S. culture - they are a pleasurable way to entertain your friends on an evening out.

When we reach sophisticated Hampstead it is obvious we are out of place. In this select area of London, it is surprising that limos like this are even allowed.
...
In Westminster, crowds of tourists gather to stare at us as we pause at traffic lights. We can see them, but they can't see us, of course. The front of the vehicle goes through on green, the back scrapes through on red, and we fill up whole yellow box junctions.
...
Togetherness is what limos are all about - originally they represented a rather dangerous, downmarket glamour.

Now, for most people, they are about friends, family, comfort and keeping the party together - a wonderful, if expensive, way to sidestep the congestion, toe-treading and transport rage that lurks outside on the litter-strewn streets of Britain today.

'I'd rather do a stag night any day,' the driver Pete Spiteri, 46, tells me later.

'Women always want to molest me, sticking their boobs and bums through the hatch and jiggling them at me. All I can hope is that later, after a few drinks, they'll go to sleep.'
