2000 Civic Si, driving about 70mph... I set the cruise control and the car starts accelerating. I get to 80mph, bewildered, I turn the cc button off (nothing happens), then step on the brake (nothing happens). Going 90mph now and starting to freak out. Put the car in neutral, the car starts bangin off the rev limiter. Bah Bah Bah Bah Bah for about 45 seconds, then the cc finally lets off. WTF?

Scary!
