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.
If you're making a turn push the lever farther and it will keep blinking until the steering wheel starts to return to center. If you're just edging sideways into the next lane, a little flick will give you the few seconds of blinks and stop, because the wheel doesn't turn enough for the other system and you might not realize it's still blinking mile after míle.
I do wish the blinks were a faster tempo, more chances to alert others quickly.
