It’s sort of a flawed opinion. If you’re never charging at home and doing a lot of driving, a hybrid won’t make much difference and might cost more. If you’re conscientious about charging when you can and mostly drive within range of your battery’s capacity, it can be almost as effective as full electric. Stats indicate most PHEV owners use the the same way you would use an ICE, car, which is more expensive and a bit of a waste.
