“I was driving north on I64, and a car in front of me suddenly stopped. Cruise control was on, but when i applied the brake, my car did not stopped, and cruise control speed up, before decreasing speed. Instead of turning off, and allowing the car to slow down. I had to swerve, causing to go off on the side of the highway, and held my foot on the brake for almost a mile, along the side of the highway, before the car came to a stop”
