Over 15 years driving, here. I use blinkers all the time. I feel weird if I change lanes without a blinker, even if I know for an absolute fact there’s no one around me… Or even any that can see me. And I mean, I’ll even use it when I do a little road rage for people camping in the passing lane and I pass them on the wrong side, cutting a little close when returning. That being said, a driveway is something I’d make a joke about among friends. It wouldn’t make me judge you as a driver. I’d use the rest of your driving as my judgment material.

My 2 cents on a topic you didn’t ask for: Do not hold down the passing lane. It makes me a little irrational, but only with a totally clear line of sight. There’s plenty of dumber morons that suck at it, so camping sprinkles a little chaos into the hierarchy of the lanes. It does not matter how your speed compares to the limit.
