This will just make NASCAR better and better. Imagine the "race" when the goal is to go as far as possible on one tank of gas. After the Volt pulls over a few minutes into the race, the Prius jockeys will be drafting off each other at 40-42 mph for hours, trying to get that extra lap before the fuel tank runs dry, and the excitement will be totally different from today's races. Plus, at 40 mph, the sport will be completely safe. Obama will fundamentally transform NASCAR just as he transformed the largest, strongest economy in the world.
Think of all the gas they will save when 4 cylinder cars drive 35 mph around the track 5 laps. ;-)
