The Bolt competes in the same space as Leaf, Prius and Volt. It is a green car. That is a niche market. There are a lot of people who care about green, but they are still a small minority in the overall market. People who like these cars based on their lesser known advantages of performance, convenience, etc. are an even smaller niche.
The typical consumer doesn't care about how green a car is. He cares more about either if it is affordable/reliable/versatile or its prestige. As long as gas is cheap, these green cars lose in both of those categories. Plus, marketing these is an uphill climb because people are understandably worried about range and battery longevity. The Tesla will at least have prestige going for it. Tesla got that part right. They understand that prestige, not green, is what will sell cars.
So unless/until gas gets expensive, these Leaf/Prius/Volt/Bolt green cars are not going mainstream. Companies (other than Tesla) will make as few as possible to get the environmental credits they want, and sell the cars as best they can. The niche market will absorb a certain volume, but if production is higher than that, it will take discounting to move them.
That is going to be true until something changes the market like higher gas prices, (maybe a supply shock or a large tax increase on fuel or carbon), or a sudden and highly visible environmental disaster that makes average people care about carbon emissions (the fact that global warming has not achieved this means it will have to be pretty impressive and undeniable). Or on the supply side, the EV battery gets cheap enough so an EV has a lower sticker price than an equivalent ICE car.
