In the article they talk about what I think is the best option, essentially a Batman style toy: a GPS tracker that can be fired at a car. I'm not sure the model they describe is the best option, but helicopter + fireable GPS tracker seems like about as good of an alternative as you're going to get.
On the other end of the spectrum, a lot of the surveillance "stuff" like the Stingray trackers could also help with this.
