You're not alone, it drives me insane. With driving directions, why does it need to tell me to make a right off my street onto the main road when I've done it a thousand times? No matter where you're going from my house, the first three directions are always the same unless you've got a helicopter.
That's not to mention the overly verbose, repetitive, and late instructions whenever you're taking some ramp from one highway to another. God forbid you try to have a conversation during that.
It's about the speaking itself. I have a hard time with auditory discrimination so I have difficulty speaking if others are as well because I can't properly listen to myself speak.
I wish there was a level of detail slider for the navigation system, because by default I think it's overly detailed and verbose in many instances. An option to skip the first n instructions or any instructions within an x mile radius of my home would be nice too. I don't need the navigation to tell me how to get to the major highways near my home, just which one to go to.
