Drivers License?

I don’t know whether the seizure of my license is a legitimate concern.

If you drive similarly to the average Tijuanense or Chilango, I would suggest that it would be a distinct possibility in your future. Compared to other parts of Mexico and certainly compared to road-rage filled Southern California, I find the drivers in Zihuatanejo to be quite careful. Every once in a while, a combi driver is auditioning to be the next Mexican Speed Racer, but that is the rare exception, thankfully.
