I connected to mine via ADB over ssh to remove the stock launcher and install FLauncher. It kept trying to launch the google launcher anyways so I removed play services and some other stuff also and just replaced the stock youtube with some third party client. Its been working ok so far! Every so often it will boot to a black screen (I think it fails to start the launcher) but a reboot fixes that.

Is there any more in-depth analysis to show how many EVs would be needed to make this feasible, how this would work with time of day use of power from commutes vs generation from solar power, how long the grid could stay powered this way, impact on consumers range, etc? I think the concept seems simple at first but would it actually be resiliant relying on just EV batteries? A cloudy week could see everyone run out of power, for example.
