Besides, it's not a "the machine says so and not even the Supreme Court can overturn it" scenario. If there's genuinely a reason to cross into the intersection while the lights are red (such as there having been an accident, and a cop is temporarily managing traffic) the ticket will be waived. Heck, there will probably even be photographic evidence of it!
Most countries even have cops judge the tickets, just to already filter out those weird cases. The registration is done by a robot, but the policing is still done by a human.
Or, a deer jumped out on the side and you briefly looked away at it.
Or you could tell the driver behind you wasn't slowing down, so the safer option is to go.
Or. Or. Or. Real life is messy, and there's a million reasons to go though a yellow instead of slowing down.
This is common in the US as well. The machine takes the picture, filters out the illegible ones, and sends the rest to an actual officer who will issue the ticket.
