Here is a thorough description of the what the API can do - https://timdorr.docs.apiary.io/#
My programming skills are not good enought to write a module to use that APi to display information about the car.

A module that displayed lock status, location, charge level, location… would be very nice.

I presume it would be quite trivial for a good programmer. The Nest API used for the NEST module seems quite similar.
