get some red and blue lights in the corners and some strobes. Then you can pull over anyone in your way.
I actually pulled someone over in my mom's Maxima. I was speeding down some road (hey, it's a fun car to drive) and I pulled up on someone's ass real fast. I had some blueish headlights at the time. Immediately he slowed down (pissing me off) so when I made a turn, he saw my blinker and turned too. When he pulled over, I just passed him and being near my destination, I just kept going. I thought it was hilarious, the guy must have been old or something.
