We often complain that we can't get simple tech that we take for granted in cars in our aircraft, but as I'm driving through bands of rain it occurred to me that my fancy 16" screen gps turns the line yellow because there is crap weather ahead, but doesn't show a radar picture, or any other useful weather data. And I've not seen any that do. Granted, it's not as important in the car, but it's a nice feature that's lacking in most (all?) gps software for cars.
