You can always tell when an illegal Mexican is involved in the wreck, he gets out of the car and runs away. Provided he can run.
I am not sure if it is because he is illegal or because in Mexico the one who is still alive is at fault.
My husband was recently involved in a hit and run on the way to work - a guy ran a stop sign on a side road and pulled out in front of him - hubby could't stop fast enough on the wet pavement. Thankfully, he wasn't hurt, but there was about $5000 in damage to our car. He went to the police station in the area with as much information as he could remember about the car - he got a partial license plate and knew the color and make. The guy there pretty much laughed at him and asked him if he knew where he was (for those that know the Milwaukee area, he works near the Domes).
The cop told him that if it was a hit and run it was because: 1) the driver was drunk 2) the driver was illegal 3)the driver had illegal stuff in the car. or 4) all of the above.
