How to run Android Automotive scripts

Question

I am trying to run/test these Python scripts that can be found here: https://android.googlesource.com/platform/packages/services/Car/+/master/tools/emulator

But I am not sure how to run them. I have setup an emulator on Android Studio, as well as on my Android device via adb, but I can't seem to run test the scripts. Can someone explain/help how I can run these scripts?

Tried running on android studio via emulator Tried via Adb connection to android device

I believe this is the main script that runs vhal_emulator_test.py

Connecting local port 46495 to remote port 33452 on default device
Traceback (most recent call last):

    self._vhal = vhal_emulator.Vhal(types)
