Guadalajara Speeding ticket

Jan 18th 2018 we were driving through Guadalajara and got stopped by motorcycle policeman. He said were were speeding, doing 88klm in an 80KLM zone. They got my picture on the radar cameras and since we had out of country plates, they have to stop me and issue ticket. I told him I would take ticket and pay for it next day to get my drivers license back which is common. He said I was not able to drive my pick up since I would not be in possession of my drivers license and would need to have another person drive. That presented a problem as my insurance may not cover them and they were Mexican nationals and could not drive foreign plated vehicles. The option then turned to getting the truck towed. I complied with getting it towed as I had no choice really. Then the option for me to pay him and he would pay ticket, but only if I agreed it was acceptable. The fine was 2,400P. The money was put into some papers and handed to policeman who returned my drivers license and ownership and we left. I hate doing this and scold anyone I hear to takes the bribe and wish I could relive these moments and do things differently. This is our 15th year spending our winters in Mexico and hope for many many more...
