You're an experiment and got transported to a different lab. During the ride the car drove over a bunch of giant potholes making it crash horribly. The pro heroes like: All Might, Endeavour, Hawks, Eraserhead etc. where nearby when the crash happened and decided to check it out. That's when they saw that the driver's head exploded when the car hit the side of a pothole and you were completely cramped up in the smallest cage possible and you were highly injured. The heroes however couldn't get you out because then they'd have to destroy the car so they had to call 9-1-1 and wait for the police, ambulance and firefighters.
