I WAS DRIVING MY 2018 ALFA ROMEO GULIA QUADRIFOGLIO IN HOUSTON, TX. I WAS HEADING ON I-45 SOUTH TOWARDS THE RAMP TO MERGE ON GRAND PARKWAY 99 WEST. ONCE I WAS ON GRAND PARKWAY 99, I PLACED THE CAR ON CRUISE CONTROL. IT WAS RAINING VERY HARD AND THE CRUISE CONTROL WAS SET TO 75MPH. SUDDENLY, THE CAR HYDROPLANED AND SKIDDED SLIGHTLY TO THE LEFT AND THEN IT SPUN RIGHT 180 DEGREES FACING THE ONCOMING TRAFFIC. NOW THE CAR IS GOING IN REVERSE FROM THE FASTEST LANE, TO THE SLOW LANE, THEN THE EMERGENCY LANE, AND FINALLY; THE CAR SLID OFF INTO THE SLOPING WET GRASS DOWN THE SIDE OF THE FREEWAY AND CAME TO A STOP WHEN THE SLOPE SUBSIDED INTO A FLAT GRASS SHOULDER. IT WAS ALMOST 200-300+ FEET AWAY FROM THE INCLINING CONCRETE FREEWAY WHERE I SLIPPED OFF ONTO THE WET GRASSY SLOPING SHOULDER. THE CAR CAME TO A STOP AT THE FLAT PART OF THE GRASSY SHOULDER AFTER AN ESTIMATED 200-300+ FEET. I HAVE ATTACHED THE IMAGE SHOWING THE START OF THE SKID TO THE FINISH WHERE THE CAR STOPPED FACING BACKWARDS. I WAS ABLE TO DRIVE THE CAR OFF THE GRASS ONTO THE SERVICE ROAD AND WENT TO AN EXXON GAS STATION (22207 KUYKENDAHL RD, SPRING, TX 77379) TO CHECK THE DAMAGE. LUCKILY I WAS NOT HURT AND I DID NOT NOTICE ANY DAMAGE TO THE CAR. IN MY EXPERIENCE, I FIRMLY BELIEVE THAT THE CRUISE CONTROL IN THE CAR DISABLED ALL TRACTION CONTROL AND ANTI-SLIP CONTROL IN THE CAR BECAUSE NON OF THOSE SYSTEMS INTERVENED. WHEN THE CAR STARTED TO HYDROPLANE, I DID NOT FEEL THE TRACTION CONTROL STOP THE FASTER WHEEL FROM SP
