I was always surprised they had an emissions test but no safety.
I'd say let's all just hold everyone to a reasonable standard on both but "reasonable" and government don't seem to go together. I still don't believe a 65 Impala, starting today, can ever create as much pollution as it takes to make one Tesla, but I'm open to being proven wrong.
In my non college educated opinion, an existing older vehicle that's more dirty to drive still generates far less pollution than building a new modern cleaner running vehicle every 3-5+ years. It takes a lot of energy and materials to build a new vehicle vs keeping older ones on the road.
