Hard to argue over who is the best worst. Until auto companies are forced, by government or competition, they are content to complete barely passing assignments.
The average American consumer could care less about efficiency for the most part. The BuZzy4orkXs is a prime example. It takes two of the three; either brand loyalty, Elon vitriol or stupidly to buy such an inefficient, slow charging compliance car.
GM was decades ahead in electrification before they axed the EV1. Toyota had a jump with their hybrid tech (that they did not develop themselves). Besides Chevron buying up NiMH patents there were work arounds, much progress could have been made but they fiddled for too long.
Interesting times are coming to the auto industry. I’m all for worker rights but the big “3” are in for some serious pain. Unless the government can keep Chinese branded cars out, its going to be worse than the 70s for Detroit. They knew this was coming, just like Exxon knew.
