Seriously. Check your police blotter in the good old fashioned news paper. How many incidents do you see of traffic stops with Hispanics that resulted in arrest because of either no license or no valid drivers license? Last week I counted 10, there were 27 total police reports. I'd dig further into population demographics, but for whatever reason I cannot find stats regarding licensed drivers in the US that breakdown by race.

Mexican's won't get a drivers license... do you think they will get a scrappers license? I'm going to say NO.

It's called PEX. Its been used in the UK for years. US home builders finally realized it is cheaper, but still not up to code in some areas.
