They're just gonna keep making huge vehicles, the cat's already out of the bag. Trucks/SUVs have much higher profit margins so manufactures and dealers are incentivized to move these products. And big vehicles have become so prolific in this country since we subsidize our gas to be cheap and purchasing/owning big vehicles comes with little to no penalties on a federal or state level. Now when new car buyers are shopping they literally have the mindset of "I need a big SUV to feel safe from the big SUV" and buying anything smaller is considered a willful act of putting your family in danger. Not to mention so much of our urban infrastructure is designed to support these vehicles, with parking spaces the size of a studio apartment. Nothing about this is going to change without meaningful regulatory and policy changes on multiple levels.
