I think they’re overwhelmingly being chased by a police vehicle after a lawful request to pull over and stop.

The fleeing driver is choosing to turn that lawful stop into felony fleeing/eluding if they choose to attempt to flee at triple digits.

This is very much an “it takes two to tango” situation.

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.
