The goal of transitioning to electric should be to maximize electric use on short trips, relegating ICE use to long trips only, and minimizing maintenance costs. Electric minimizes routine maintenance but have a huge back end cost when the battery fails. ICE cars have an exponential maintenance curve as the car ages, but is overall cheaper than replacing one battery in a electric. Hybrids, while they have the worst of both worlds, they still have less overall maintenance and a more manageable battery cost when the battery eventually fails.
Hopefully, it means BMW is going to bring back the Range Extender ICE in their electric line. Although it didn't bring much range to the table, what it did do was bring a fully electric powertrain with no crazy ICE coupling to complicate things. It was simply a motorcycle engine directly attached to a Generator feeding directly to the battery to maximize generator to battery efficiency. It just needed a slightly bigger gas tank and the car would have easily sold twice as much. This design gave you most of the maintenance advantages of an electric with smaller ICE maintenance costs (since the engine was simpler and there's no complicated transmission) and a smaller (which means lower cost) battery.
This coupled with more efficient motors and you would have a very interesting design, and when I mean more efficient, I'm talking about space efficiency. This was one of the reasons I was interested in the Lordstown Endurance because it's hub motor design freed up a ton of space in the mid section of the car, which could be used for a larger generator setup or at the very least a larger fuel tank for longer trips. Also the Hub motors were crazy simple to replace if issues arose since it was basically removing the wheel from the suspension.
The other thing that has to happen is industry standard modular battery packs. There needs to be an industry standard for battery sizes and connectivity to the point that swapping battery packs is like swapping a traditional car battery. Once you get multiple companies making cars using the same modular design, battery costs will drop significantly to the point that people will be more comfortable owning an electric car longer than 8 years. This will also benefit PHEV's at first but once you get the battery swap to under $10000 for a long range electric vehicle, The electrics will displace the PHEV's for most drivers.
