Massachusetts followed closely by Jersey.
NJ is horrible; too many drivers that were riding animals half a world away within the past year (yet somehow getting licenses). An Indian friend described how he wanted to get his license when he visited India for a wedding; he said NJ would give him a license if he had an Indian license. Sure enough, he was issued a NJ license without ever taking a test here (written or road); he had never driven on the right side of the road. Now his car has a mangled front passenger rim because he doesn’t know how to make right turns...
