Chased by what? It isn't a lion they are running from. It is a police interceptor egging them on to go 100mph.
The fleeing driver is choosing to turn that lawful stop into felony fleeing/eluding if they choose to attempt to flee at triple digits.
Without both of:
- A driver willing to flee the cops.
- A cop willing to chase at dangerous speeds
The high-speed chase doesn’t happen. Both make it happen.
