It just fully depends on the driver. A PHEV which the driver does not recharge is just a heavier HEV.
But if you have less than 70km to drive every day and have a home charger, there’s barely ever any reason to use gas.
The issue is that many PHEV owners only get one because it allows them to get around regulations for driving in city centers, so they just use the cars as gasoline powered cars.
A lot of these arguments are not logical.
Yes you can have large PHEVs, but the trend for bigger stupider cars is independent of power source. You can get a PHEV Renault Clio and it’s 20% lighter than the smaller electric Renault 5. And uses 80% less precious minerals because you have a smaller battery.
The gas engine needs maintenance of course, but you do use it much less than the electric motor, requiring much less maintenance than a normal car.
The fact that people buy PHEVs for the tax incentives and use them as gas vehicles is stupid and annoying, but that’s not a fault in the technology itself.
