This is ridiculously complex, and thinking you can encode every possible eventuality in law or code is frankly not a serious suggestion. You need the "slack" exactly because it's just not feasible to do so. (Also: so many things can go wrong with your "facial detection" suggestion: internet not working, error in facial detection, broken equipment – never mind the privacy implications, or the cost of building and maintaining all of this, which would certainly be far far higher than any corruption, and still won't actually prevent corruption because drivers could still just let their mates pass without paying).
And yes, giving people autonomy also means they can do bad things. And that's something we can live with, and it's far better than forbidding them from doing good things. Your distrust of people borders on the misanthropic.
I mean yes, it'd be a safe job to have for decades. You could get paid literally doing nothing.
But also no, this is lunacy. Not only 'itake would like to strip people of their autonomy, they'd also like to strip them from their capacity to do good? That's wishing us a fate worse than death.
Not that it's possible in practice anyway. It's a AGI-complete problem, and any lesser attempts are... well wake me up when any software system implements exceptions and slack around their rigid rules.
