That's true, but having recorded footage of the chase would make it easier for the prosecution to prove who was driving the car as they would have the driver on film exiting the vehicle's right hand side.

I also think you maybe under the misapprehension that the helicopter was dispatched exclusively to track down your car. It's more likely that one was in already in the area. And from the description you've provided us; it sounds as though they'd be more justified in their actions if they just set one of their dogs off in pursuit of your elderly car and its nefarious driver.
