I was lucky enough to get caught in the traffic snarl that was created as a result. I stopped counting AirMed helos after the 6th one took off.
The driver of the truck, of course, was well enough to bail and head for the hills prior to arrival of LE.
At my old PD in the midwest, unlicensed, uninsured, illegal drivers were the cause of over 60% of our traffic crashes and nearly 75% of our hit and runs.
No one wanted to work a dayshift on Sat Morning because the first 2 hours of the shift would be responding to hit and run or property damage accidents as a result of the drunken drivers wandering home.
In heavy downtown traffic on a friday night, I could close my eyes, point, open them and be looking at an unlicensed illegal driver. Literally. It's out of hand, and not just in AZ.
