While the custom widget renderer PR had been merged, there are a couple of follow ups that needs to be addressed to fully support Android Auto using new renderer.

This ticket is tracking adding onClick/onTouch to detect if user interacts with widgets. At the moment it's blocked by lack of support from the Android Auto API's. The ticked tracks feature request from Google.

This is where it's being added. But I tested it about a month ago and it's not working yet.

Commenting to also ensure that we will be able to add an api to MapboxCarMap or MapboxCarMapGestureHandler
