Renting a car has become an absolute nightmare recently. They overbook and chances are good that when you go to pick up the car they won't have one, or at least not the model you reserved. This is especially so at times of high travel demand like holidays.
What we need is to normalise small about-town cars for groceries, commuting, and dropping off kids. Something like an e-Citroen.
For long-haul you still want ICE with hybrid.
