Maybe. The scrolling widget has some advantages over a keypad. It has strong association with the physical odometer in the car (not all cars have odometers like this, mine does not, but it is a very strong association). The user doesn't have to find the label 'enter mileage here' -- it's obvious how to enter mileage, and if it spins (I don't know, but I hope so) it would be intuitive. The user doesn't go through a context switch away from the main screen to use a number pad. On the other hand, a power user is going to eventually associate screen locations with actions and never read the labels again. That form of association may be the reason for the brightly-colored buttons.
