That’s probably sooner than you think.
DOTs are intercepting trucks with drones and measuring wheel temperatures and other metrics to do targeted enforcement rather than pulling over every truck. There’s also pilots of road sensors that can weigh trucks and perhaps other metrics.
Which really is just a revenue game but one with a good eough pretext you can sell it to average dumbass voter. All the "serious" overloading is non-CDL box trucks anyway and has been forever. The road scales are easily gamed, or just avoided.
