After 10 years of living and driving in the US, it’s finally dawned on me that, despite outward appearances, the British “indicator” and the American “turn signal” don’t mean the same thing at all.
For Brits, the flashing light basically means: “I’m terribly sorry to be a bother, but I just want to let you know that I’m about to make a turn any second now. Stand by…”
For Americans, on the other hand, the flashing light means something along these lines: “Hey! Check out this turn I’m already halfway through making! Woo-hoo! DON’T TREAD ON ME!”
At least, I think that’s how it works. I’m still trying to crack the code.
If I’m right though, I’m very thankful that my American friends occasionally make use of their “turn signals” to draw attention to partially completed vehicular maneuvers that I might otherwise have missed.
