True hybrids that can get 50+ mpg are better than ICE for sure. But plug-in hybrids are not the way forward. You can travel 20-30 miles on the tiny electric battery then it’s a full on ICE vehicle and mpg usage. Environmental impact on those plug-in hybrids is way worse the more miles you drive, really only a good fit for low mileage drivers that will be consistent with plugging in at home.
