Throwing an object unto the car or disabling a tire at a gas station for example, happens here in the DR, especially to tourists in rental cars. Happened to my Dominican friend and her Swiss husband where they offered a new tire at a close gas station. The girl was familiar with such scams and they took the spare tire all the way to Santo Domingo instead of buying tire, to find out a new tire was not needed and it was an easy fix.
I got robbed of electronics in my back pack at parada Jacaranda where they used a device to stop my car from locking, and a guy followed me while on the phone, probably communicating my location to his partner who went through my back pack and took out the electronics so I wouldn't notice anything stolen right away until I arrived in Santo Domingo. I saw the surveillance video later and it was obviously an experienced routine by professionals.
It doesn't happen often but it does happen consistently enough so that locals are very aware and some drive packing.
