All windshield glass sold in the US is laminated AS1 glass consisting of two layers of glass with a plastic laminate sandwiched between. The thinner glass really doesn't have anything to do with better manufacturing processes; it's part of the overall weight savings on newer vehicles.

As an interesting side note, in the 80s there was available, for a short time, a type of windshield with four layers. The fourth layer was a plastic layer on the inside of the windshield. The idea was that it would reduce injuries during an accident. It was expensive and prone to damage from improper cleaning, and it didn't significantly reduce injuries, so it only lasted a few years.
