Records 10 samples per second: speeds, acceleration, throttle, rpm and gear.

Sounds are synthesized live from each engine's layout (cylinder count, firing order, exhaust resonance). They are an approximation, not recordings of the real cars. Keep the screen on while driving; iPhone stops web audio when the screen locks.
