That and from what I understand of them they only cover about 25 miles. The reason to get a plug in hybrid vs a full plug in is generally because you need to drive more than that on average. I have a full electric from 2015 with a horrible battery, and on a single charge I can get ~50 miles at most in greater Atlanta area, GA, USA.
That's mostly fine for me, but I once looked up the plug in hybrids for trios etc, and I sometimes forget to charge and have issues having to charge on the road. A plug in Hybrid would have saved me those minor problems, but not because of the electric part. I have a feeling anyone using a plug in hybrid is barely using the battery part of it. I get by because I mostly use the car for shopping, so on average it's once or twice a week, all within 1 battery's usage a day.
