What is the name of this movie?

Here are the things I remember about it:
There was a black car driving around without someone in it.
The main character found a gun in the black car.
Someone was trying to speak to the man, and phones would ring as he passed them. After a while, he shot at the phones with the gun he found in the car.
At the end it turns out that there was some AI project going on or something.

It was on TV a few years ago, but I forget the name.
