I used to have a Garmin with an English woman's voice on it and loved it. Too bad it's now outdated.
I love the GPS with the English woman because:
1) She actually knew where she was going
2) She did not get upset or yell at you if you made a wrong turn
3) And when she was not giving instructions she'd shut up.
But in all seriousness, my wife does all the driving for us, and except for #2, she's like that English woman if I was driving, as she is quiet and not like the stereotypical talkative wife. I'm more the yappy one, actually. But she is quicker on the reaction and a better intuitive sense where to turn than I am.
