What i would like to see is something like Raspberry Pi control.
So, you can fully know what is on the board, and you can know fully what is the program.
And you can go in and wipe it clean yourself, and then reprogram it.

Or else, we build tiny, independent control modules.
Like a motor control that can take any type of power input, and gives only input and feedback of motor speed.

The remote kill switches makes my blood boil.
The car you paid for, is not your own.
