Florida went through this with Haitians. Best trick was to find an elderly person not paying attention (pretty easy), pull in front of them, and either slow down or hit the brakes (usually without the lights working). Lots of fake moans from a car usually filled with family members. Don’t know why but the scams stopped to a large degree, probably because police and insurance investigators got wise to it.
Ethnicity coupled with government protection allows them to circumvent the system, get some quick cash and if theres a problem the cry racism and move to the front of the line.
