Not without the 12V. I’m pretty sure most of the internal electronics are dependent on that working. There’s an access port so you can “jump” the 12V with another car, which I think would then allow you to open the door though.

I don’t disagree there!

You can also “jump” the car to open it via a 12V access port in the front.

Some quick googling looks like this is real. Looks like it was this deleted post.

Basically VR/mixed reality runtimes
