how to sell new cars with new controls

You know the traditional controls of a car. Steering wheel, 2 or 3 pedals and a shift lever. There are alternative control systems out there with several advantages. But how will you convince people to buy them?

Here's my idea for a TV commercial that tries to sell cars like that. This one concentrates on decreased braking response time. I thought of this when I saw an article about a combined accelerator-brake pedal being developed by a large car company. It's a simple mechanical device. The pedal acts as an accelerator when you extend your foot (the foot part of the pedal pivots) but it acts as a brake when you extend your knee (the entire pedal assmebly moves forwards). If the brake is activated, the engine automatically goes to idle. The main advantage is that you can activate the brakes a few milliseconds faster.

Here's the TV commercial. 2 drivers, one is a famous race car driver who is not wearing his helmet (close up on the handsome race car driver's face), one has the helmet on and face is unseen (like the Stig in top gear). 2 identical cars one with and one without the new device (both with antilock brakes for some uniformity). You attach a small red light outside and in front of the windshield. The light will be visible near the top of the driver's field of view. Red light is controlled by a radio signal from a third party, maybe in a chase car. Have the 2 cars side by side on a straight track going say 100mph. Suddenly without warning the third party activates the red light. Both drivers now have to stop in the shortest distance possible. Hopefully the new device beats the normal car, maybe by 1-2 car lengths or so. Race car driver gets out and shakes hand of other driver. Other driver takes off helmet ---- it's the race car driver's grandma!!
