Remember how VW cheated the EPA tests? These have the capability to be programmed far more deviously.

A test with the the system clock rolled back to election day, with votes fed in at a normal human rate might be good enough to catch lazy programming. If they're set with fuse-like mechanisms to only cheat once until reprogrammed, only a code audit or test of a programmed, but unused machine could catch nefarious actions.

Anything more technologically advanced than a printing calculator should be illegal in an election. I will also accept arguments that we draw the line at lightbulbs.
