I don't know if anyone has noticed but automakers seem to be switching to red rear turn indicators as oppose to orange ones. I am aware that in North America rear lights can only be white, red, and orange. To me red should be reserved for the fog/parking and break lamps, while orange is strictly for turn indicators (and white obviously for reverse). People are going to get confused when they see a flashing red light that refers to a lane change while the driver ahead intends to slow down.
How is that confusing? The turn indicators pulse on and off, and on one side of the car only to indicate the direction of the turn. Braking lamps come on full, no pulsing, on both sides of the car.
Perhaps an idiot focusing on colour only, and ignoring all other visual data, would be confused... but really; if they're that easily confused should they really be driving in the first place?
