I don't understand how that's possible. Like, driving school has ingrained the turn signal reflex into my arm so well that I sometimes even feel weird not using a turn signal when making a hard turn on a road without crossroads. And changing lanes without a turn signal literally can't be done, my brain feels. Don't driving schools in the US do that?

I can only imagine the other dumb shit that happens in your life because of her

Where I live using turn signals gives inconsistent results people don't usually use them and its usually fine, I offer forget and is usually fine. But a lot of times, using my turn signal makes no difference. They like to ignore it or purposively get in your way
