“I can't believe I experienced that .. My car all of the sudden jerked on the freeway and started shaking . I seriously thought we had an earthquake .. Then it accelerated and the next thing you know I'm going 25 miles and hour .. So glad I was near an exit I put the car in neutral rolled down the hill , made a turn and shut it off .took me a minute to gather myself .. What if I was in a middle lane ? What if someone couldn't press the breaks in time🤦🏻‍♀️🤯😡...”
