Get all cars out!

This problem is based on a famous mobile game called parking jam. Here is a video footage from the game play.

In order to define the rules better, I decided to change it up a bit. Cars, walls, and empty spaces are now represented by characters on a grid of string. Each car consists of an arrow spanning two adjacent squares with the charset <>v^|-. Walls are marked by *, and the exit is marked by =. Here is an example input:

********
*<-|->^*
*  v<-|*
*<-  | =
* |-&gt;v *

********
*<>^<>^*
*  v<>v*
*<>  ^ =
* ^<>v *
* v  <>*
