Dinuba is a rural agricultural area in the Central Valley.
Reports are that the car was carjacked - i.e. taken from the owner by force or threat of violence. You don't just let people capable of doing that go about their merry way.
I know the criminals would prefer that the police abandon a chance to catch them. What I don't understand is why anyone else would feel that way. Only large cities have helicopters, after all, and even then helicopters can't be everywhere.
As far as cars, I had (sold in June because there's no way to get a family of 4 in it) a car that could just about get to 150 MPH, and I've never once run from the police. When they nail me I pull over. Simple enough.
