It was such an unnecessary change. I hate how when you manually cancel the blinker it's all too easy to hit the opposite direction. It's not a motorcycle, there was no need to make the stalk constantly return to center. I don't mind the three blink option because you don't have to shut it off for lane changes.
I've never had a problem with the blinkers on the WRX but there is probably a couple of reasons for that. Firstly my car previous to this was a Commodore (GM) that had the same lane change feature except that it flashed 5 times. The other is that our cars (AUS) come with the stalk on the right hand side so it's more natural for the right handers (I always struggle with euro cars and trucks). I love the lane change feature and am leaving it on.
Idk why Subaru didn't just use the same stalk they have in all their other vehicles. Out of all the features they could make unique to the WRX/BRZ, they chose the most obscure thing lol
