My wife has been reporting experiencing nausea, dizziness, sleepiness and headaches during and after her drive home from work throughout October/November 2021and into December 2021. Our vehicle was involved in a high speed collision on December 24, 2021 while traveling EB on I-90 at approximately MP 101. I was driving at the time. It was at about 3:29pm. I couldn't quite recall what had happened and I was disoriented and confused for some time after the collision though I hadn't hit my head. Everyone else in the car had fallen asleep despite being well rested and it being the middle of the afternoon. My symptoms and condition were the same as oxygen deprivation. I believe exhaust has been getting into the cabin of our vehicle and causing my wife's symptoms and caused the accident. The vehicle is totalled.
