Great article, that proves that automotive ideas are not new, but advances in technology make those ideas better. Case in point, the new automatic transmissions are basically overdrives in the top gears. Five speed autos have 4th and 5th as OD. If it's an 8 or 9 speed, the last 3 gears are OD. Oh yeah, the Model T transmission was nothing more than a planetary transmission that was manually operated. Ain't technology great!
