"Well, as you know, General Motors does not make hybrids. Ford only made 4,000 hybrids last year"

Ed Markey's quote is describing the absence of hybrid automobiles produced by General Motors and Ford. He is highlighting the truth that General Motors does not produce any hybrid automobiles, while Ford only produced 4,000 hybrids last year. This is a reasonably small number compared to the total number of cars produced by both companies. This quote is most likely suggested to draw attention to the requirement for more hybrid cars to be produced in order to minimize emissions and help the environment. It is also a tip that the vehicle industry requires to do more to lower its environmental effect. By producing more hybrid automobiles, companies like General Motors and Ford can help reduce emissions and make a favorable impact on the environment.
