The NYS DOT has changed a number of its guardrail standards in the last four years...

Interesting timing.

You should read the details of those changes before making any judgements about what they involve. The link you posted shows dozens of changes dating back to 2009. There are many reasons why design standards change over time, and the ones I've dealt with in my professional work often have more to do with the constructability of a barrier than its performance under stress.

I am a civil engineer. Some of the documents in that link you posted were signed by my peers in the industry.
