Does TN not have a solid department like Kerala MVD?

Recently many of you might've come across this viral video where a Kerala MVD Inspector pulled out his S24 Ultra in order to document a violator. I noticed that even though they're from the MVD which also issues DLs, etc. they're also primarily in charge of working on field to catch and fine violators. They even have a khaki uniform just like Police dept. With these thoughts in my mind, I recently watched this movie called "Driving License" in Malayalam which stars Prithviraj. It looked like Kerala MVD Inspectors had more authority than their TN counterparts (wait, does our RTO Department even have a role called "Inspector"?). The obtaining DL process also looked like that of Germany's. Meanwhile, here in TN, our RTOs just sit in their office all day, signing papers, with a constant inflow money under the table. They wear plain white shirts, they're old & bald (no offence, my zonal RTO was), they basically appear powerless. And the traffic violations are entirely the responsibility of the Traffic wing of the Police Department. Why are our standards so low?
