The cars are literally equipped with a computer and a touchscreen these days, there is no justification to mandate an external computer or diagnostic tool to be able to do basic service such as a change of brake pads.
Someone engaging this mode by error or stupidity, and then causing an accident makes me think some things should remain lock behind some "I know what I am doing" barrier, which the subject of the original link seem to not have scaled above, as there is a simple way to brute force the electronic break, no expensive tools needed.
