I use it literally everywhere out of habit, I got made fun of for using it when pulling out of my moms driveway once lol
The only reason I won’t possibly use it is when I’m in a turn only lane at a red light and don’t want to listen to it for 3 minutes
Most people I find only use it 75% of the time at best.
I’m 2.5 years into driving and am curious if it’s just what semi-new drivers do or if I’m the odd one out.
Sure. It’s better to develop this habit and use them automatically, without thinking. Sometimes there are no cars around, but pedestrians want to know your intentions too. And even if you don’t see anyone, it doesn’t mean there’s nobody around.
Sometimes when I’m feeling adventurous, I will change lanes without using a turn signal (only when I am 99% sure there is no one around). For the other 99% of the time when I am feeling non adventurous, I will use my turn signals.
