Car swerving out of control: i was driving east on the mass turnpike on a somewhat wet evening, 2/25/18, through mist, when i drove over an area of the highway that had a patched surface. i was gripping the wheel with two hands at 4 o'clock and 8 o'clock. my hands, including my thumbs, were wrapped around the wheel. as the car drove over the slightly uneven surface, it began to swerve, going a bit out of my lane. it swerved 3 times before i was able to regain control. other cars avoided me, preventing an accident. i am an experienced driver and found this event to be quite unusual. i called my husband right away to express alarm.
