It's easy to say 'you bought the wrong car' and leave it as that. It is not always that simple.
For example in my own case and why I settled on the C-Max is because of the following:
1) There were no useful all EV vehicles at the time. The Bolt did not yet exist, and even if it did it would have to have been purchased new or lease. The Tesla Model 3 was still in production hell.
2) Where I live, there's STILL no options for decent fast charging once you get outside of the metro area here. We're just now seeing announcements from Electrify America that they are planning a few DCFC spots in strategic spots along a couple highways here that will FINALLY make owning an EV at least somewhat feasible.
3) The only other good PHEV option at the time was the Volt and it would have been a no brainer except for the reduction in cargo space and the ridiculous battery hump in the back seat. I rather prefer the hatchback style or in a compromise a CUV.
4) No luxury owning more than a single car per person due to both space and finances. Got to have a practical car that commute and make longer trips without any major compromises.
I think the whole 'piston rusting' is hyperbole at best. We're not one of the older members (whose name I forget and don't care to track down) who went to extremes to maximize their EV usage and even with that said I doubt rusting or any other degradation is going to be an issue within the set time frame Ford programmed for the stale fuel burn mode.
Again as a personal note: I do go on longer trips about once a month or at the very least every other month and go to my brother's place about once a week which, while only 10 miles away is mostly highway so using the ICE is a must.
With that said if my daily commute fits within one full charge even using the battery for heat, why shouldn't I use it and take full advantage? The full 5kw+ load only lasts for 1/2 mile at most and drops down quite quickly. Quite comparable to AC usage I've seen with outside temps at 95+. Sometimes the draw may be enough that eventually I do run out of charge but I do make note of the forecasted temps that day and anticipated heat use and will likely use the ICE completely the drive in during the morning when it is coldest if I know I will end up using heat later in the day. Better IMHO than making it about halfway home in the afternoon and having the ICE run for only the last mile or two in stop and go traffic. I do at the very least make a conscious effort to try to avoid exacerbating conditions that would cause it to go into oil maintenance mode more than necessary.
