A police rhino will come when you reach heat level 5!
The are the 2 SUV's driving behind eatchother trying to ram you. You'll probably seen them at lower heat levels only those are the light versions and you'll need the heavy's for this achievement.
You'll know when you've disabled one when the games sais you've destroyed SUV Heavy.
I did it by just letting them drive into me. The cop cars that where behind me pushed me free and destroyed the rhino.
YOU MUST ESCAPE THE PERSUIT!!
I would also advice that you use the infinate nitrous and speedbreaker cheat:
In the main menu press on the D-pad:
Left, up, left, down, left, down, right X (nitrous)
Down, right, right, left, right, up, down X (speedbreaker)
I also turned of "game moments" in the options menu because after such a moment I spawned right back on spikestrips.
* And it didn't pop for me untill I returned to safe house.
