This guy is VERY lucky. Last year a semi truck wheel broke lose and killed a driver a couple hundred yards ahead of my car on I-95 here in Florida. Those wheels are BIG and heavy. It happens so fast at 70 MPH there is nothing you can do but pray it doesn’t hit you.
About 30 years ago a similar incident on Rt17 in Paramus, NJ. A semi going southbound lost a wheel, it jumped over the “Jersey barrier” amazingly did not hit any oncoming traffic but rolled into a McDonald’s parking lot on the northbound side and killed some poor guy just getting out of his car.
