Lived and drove for 11 years in Germany while stationed there in the Army. Got VERY accustomed to the amber turn signals which were mandatory in Germany, and throughout Europe I believe. Back here in the US the red turn signals are a bit annoying IMO only from the fact that in some situations, particularly at night, and more so in rainy or limited visibility conditions, a red turn signal can be misinterpreted if a driver is pumping their brakes for some reason. Totally agree that US drivers unfortunately don't use near enough. When I first returned from Germany I sometimes wondered if it was illegal for a car dealer to sell a car with function turn signals, as infrequently as I saw them being used.
