The vehicles section is missing drivetrain information, which is vitally important to producing useful milage data.
I realize this has been dismissed in at least two previous posts (

The drivetrain (namely, Rear Wheel Drive, Front Wheel Drive, All Wheel Drive or Four Wheel Drive) is a major factor determining milage between the same vehicle and should be included to help people better understand the data being presented.
I understand the fundamental ideal of this site is to keep things simple, but this is pretty important stuff to leave out! Most people know generally which wheels spin on their cars, if you want your data to be useful, you should ask for that information.
