Usually they just flag events like really hard braking or other high-g events, speeding, travelling off-route if you pay for that module, and operating hours. At least that’s the easy to tattle stuff. They’re not smart enough to do anything like drive for you.

But some operators DO need to calm the fuck down and just obey the speed limit. These things usually let their manager know they’re shitty drivers before the police let them know they’re shitty drivers and they subsequently lose their DOT certification.
