"XLR8" iPhone App Turns my Toyota Prius Hybrid into a Supercar

I didn't write this app, but I hope the folks that did become wealthy beyond their wildest dreams. Here's "XLR8" running on my iPhone hooked up to the stereo in my 2009 Toyota Prius Hybrid. I mounted the camera on a tripod on the back seats secured with the seatbelts.
From the developer's description on the iTunes App Store:
Wish you owned an exotic supercar? Now you can with XLR8!
XLR8 (pronounced accelerate) is an exciting new app from 2XL Games that makes your car sound like an exotic supercar as you drive!
Connect your iPhone, iPod or iPad to your car stereo and you are off and running.
Once secured inside your vehicle, XLR8 uses the accelerometers of your device to realistically respond to acceleration, braking and cornering forces.
Select from one of five exciting engines:
Classic V8 muscle car
NASCAR engine
Ford GT40
Ferrari sports car
Lamborghini Supercar
