Driving 25 MPH around a curve when my car lost control, despite my best attempts my car would not allow me to take control or to break. My car went from 25 MPH to 60 MPH through a two lane traffic street, forcing me to swerve in and out of traffic merely missing six cars and a semi trailer truck, spinning my car around twice and facing the opposite direction of traffic.
