I'm sure this will happen. But I think your timeline is way faster than it will happen.
I highly doubt gasoline will be hard to find in most places by 2045; I'd expect a lot fewer fueling stations, but I think even at 10% of the station count, gasoline will still be convenient and easy. And, if gasoline is less convenient, you can always use gas cans to extend your range. They're not too expensive, and not too inconvenient (epa 'anti-spill' nozzles that make it hard to fill without spilling not withstanding); long term storage is problematic, but if you're regularly using it, no big deal. Most gasoline powered vehicles have at least a 300 mile range, and it's not hard to find vehicles with a larger range.
