I'm going to guess... because we can? Police here are willing to chase for almost anything in most jurisdictions. I bet there are restrictions on what constitutes a chasable offense in the rest of the world.

UK has stuff like [0] which contains a whole bunch of "is it worth it?" considerations. Also if a chase causes a death, the officer(s) can be prosecuted[1] - I suspect the nonsense of "qualified immunity" means there's no risk to a US officer for initiating a chase that ends in death.
