Not just that - top selling or not, you want to remove worse emission vehicles since they contribute a larger amount to emissions. One truck replaced with an electric version is effectively equivalent to 1.5-2 sedans, in terms of emissions per mile.
The Chrysler Pacifica PHEV has a <40 mile electric range. But vehicles like the Mini Cooper SE, all of Hyundai/Kia's EVs, and Tesla's standard range Model 3 and Y are missing out on the subsidy while gas guzzling minivans rake in the dough.
