This is definitely hitting the nail on the head. Until the technology trickles down into the lower-end models, it’s not anywhere near as much a cost savings when you have to buy way up in trim level to get electric as an option.
It’s also worth noting that electric economy is notably worse in cold climates - your internal combustion car generates heat for ~free, the electric heater in your Tesla does draw a fair bit of current.

There really is nothing close to Google Photos outside of Synology. And it’s not 100% in terms of search but it’s getting there.
You can run the Synology software via a loader on commodity hardware or on a hosting platform provided the platform supports VMWare ESXi or the like.
