I love the voice prompts that accompany navigation and I like to use them when going somewhere new. But i don't need them to tell me how to get out of my neighborhood or how to get to the freeway. I find the constant unnecessary interruptions quite annoying.
After a nice meal out and putting leftovers in the frunk. Would be great to have a little button on the interface - "Remind me to empty frunk". Next time the car is put into park and the driver door opens, "BING! - Remember to check frunk" Maybe it would even pop open.
