Are these people serious about being stopped

no but what they will do is drive after you, catch you up, drive into the side of you and send you flying to hospital.

trust me I know.
It hurts.
A lot, then you have to recover- even if you don't have any broken bones. concussion is a bitch

Since then, I dont jump red lights.
ever.

and maybe add resisting arrest (or similar) for good measure. and i might be corrected but i heard you can have points placed on your car licence. that is also a thing that sticks in my mind when i approach a red light and the urge comes over me to just continue riding
