High-speed police chases make movies more exciting. We get an adrenaline rush and a sense of dramatic urgency when we see portrayals of police doing everything it takes to take down the bad guys. In real life, though, there can be serious consequences from police chases.
A high-speed car chase carries with it the obvious risk that the fleeing suspect or police officers will crash their cars and get injured. It also carries the risk that they will crash into innocent civilians. This risk is not hypothetical – it has been known to happen in Florida.
