As I've always said, you don't need new laws to stop chasing. If they want to crack down hard, it's not difficult to do. I believe we will see more and more of this selective targeting. Ticketing is just the first part. If you have to appear before a judge and he / she does not like chasers, you might be cleaning the side of the road wearing orange as chasers go passing by. (Man that would suck!)
What I foresee are more "reckless driving-type" citations. Those are very serious traffic offenses. You could have your license suspended or be thrown in jail. It's up to LEO to determine the justification, e.g., passing emergency vehicles that are not actually blocking the road.
I also see a new television commercial coming soon: "Hello storm chasers! This is attorney Saul Goodman. Have you or a loved one been pulled over while chasing and charged with a serious traffic offense? Don't throw your rights to the wind. Call me now for a free consultation."
