It's a nightmare for car manufacturers right now - they had a gun held to their heads in europe to go diesel, then the politicians changed their minds and decided to push EV despite there being little effort made to create viable supporting grid infrastructure. Jaguar Landrover bet big on diesel and are digging out, but the chances of recovering from the diesel debacle while succeeding at innovating EVs is slim. Meanwhile dozens of Chinese EV firms are going to the wall, despite China being the big transportation growth market
Jaguar Land Rover even built a huge diesel manufacturing facility [1], finished in 2014. I visited it around that time, the site was very impressive but cost them a huge amount of money.
I don't think car manufacturers have cause to complain. If they were feeding the government incorrect data, then they do not really have moral grounds to complain when the government officials made incorrect decisions based on that data.
