Carson Hocevar caused a seven-car pileup to open the NASCAR Chicago street race. Hocevar clipped the inside of the turn 11 curve, ricocheting him to the outside wall on turn 11 on lap 3 of the Grant Park 165 street race in Chicago. Hocevar crashed off the outside wall and moved up to the inside before twisting back toward the outside wall.
