Right before Michael slides under the semi truck, the stuntman's hair can be seen sticking out from the back of the motorcycle helmet.
When Michael enters the parking garage on his motorcycle, he maneuvers around the parking curb in front of a silver Jeep SUV. 3 seconds later, the same shot of him maneuvering around the Jeep SUV is shown again.
Right before Michael slides under the semi truck, he is seen wearing gloves on both hands and his left pant leg and left sleeve are already shredded. As he slides under the truck, he is seen wearing only one glove on his left hand. Then, when he stops sliding and gets up, he is seen wearing no gloves and his pant leg is no longer shredded.
As Michael is sliding under the semi truck, the motorcycle seat can be seen on the ground behind him. When he finishes sliding, the motorcycle seat is back on the motorcycle.
