> This is normal across the world

I'm not arguing it isn't, but the thought exercise is: does it make sense for the government to take people's money if the accused can't prove it wasn't them driving the car based on a police accusation (also with the threat of jail time if you don't pay)?

I don't think that's "normal", personally.

No, because in a functioning legislature the offence would be something like 'failing to disclose details', in the same way that refusing to participate in a DUI breath/blood draw would be a discrete offence.
