how do those chase helicopters keep focus on fast moving cars during a police chase?

Feels like it would be very disorienting for the camera man and would be quite shaky from that distance out. Is there some special equipment they use?

They have mechanical image stabilization. Basically, it’s a speciality camera mounted to the body of the helicopter, with gyroscopes and servo motors and stuff to help stabilize it.

And as for *literally* focusing on the car, they use a lens with a pretty “wide depth of field”, meaning that instead of focusing tightly on an object and having everything else blurred, the focus is very loose and easy.
