Well, I support this, because it is better than nothing (or better than what we have now). But even when it would be spoken, there should be more thinking about what is a situation that should cause an alert and when is it useful. If there is a situation during a ride the least you need is a car "yelling" nerviously or telling you something, but it is even better than now: a car "yelling" nerviously and trying to get your attention off the street to the screen.

As I unfortunately can only give one +1, here is a second from me:   +1!!  I very much like this feature!!
