LEGO Drag Race Track for Hot Wheels. Intro and Qualifying Round

I discovered that Hot Wheels cars are four LEGO studs wide. What better creation to build than a drag racing strip! The strip is just over 3 feet long and uses all my greys and black tiles for the pavement. Made a simple mechanism to hold the cars and a cam gear lowers the brick one plate for the cars to roll smoothly. The track works great as sometimes one car will win and then the next it might lose or accelerate at the end. I been in a Hot Wheels racing theme addiction since the beginning of the year and have some new cars to test against the ones from my childhood....which wasn't that long ago :P I have the qualifying round shown in this video. Then the First round, second, possibly third or just go to the semi finals, then finals for the fastest Hot Wheels car in my collection.
