Default to not display Home and Work address. Think of it like this: you're driving colleagues to lunch on the spur of the moment. Why do they all need to know your address? Not safe for females is it? That's lawsuit territory. This is such an oversight that I've set a home address of a shop nearby. Another example; female has a date and has kept her employment information private. Gives date a lift, now date knows her address. If something happens to her, that's a pretty big lawsuit for you guys. It's showing it on the screen, to everyone in the car and anyone leaning in the window having a chat. I know where I work, I know where I live. No one else needs this information.

Secondly, the press of the current object status (that's the is it Still There? button) is probably the single most distracting event. Yes it needs to stay, but this needs to be as close to the driver side as possible. It's harder to look at the furthest side of the screen, especially when you're doing freeway speeds. Takes a couple more seconds at 100kph - and that's how many metres travelled without looking ahead?
