While the battery technology will still evolve quickly, early days is hardly how I would characterise it. In the UK, we are finding traction is really taking off.. There are battery charging only service stations: https://www.bp.com/en_gb/united-kingdom/home/news/press-releases/bp-launches-first-dedicated-ev-charging-and-convenience-hub.html
I was mightily p155ed off when I had a very low running petrol tank on my bike and thought that servo was my salvation.
The reality is today, battery technology is very reliable; the degradation is not anywhere as near as the dooimsdayers have predicted, range anxiety is a thing of the ignorant. They are more expensive to buy (but the gao is closing) but their reeduction in operating and fuel costs puts you ahead oif similar ICE cars in about 2 - 3 years instead of the old 5 years.
Battery technology will continue to improve through a steep curve for a whilem but the context of what we normally mean to be early days has well and truly passed.
I am holding off buying a used BEV because hopefully in a couple of months this house will goup for sale and sell, and it will be Aussie bound. But for reference, 3 year old cars on average have less than 5% degradation - most I have been looking at are in the 2 - 3 % range. With the normal distance range starting at 300km, and 500+ becoming common, I am not too worried about a 50% degradation over around 50 years (that is calcualted straight line, and I have a feeling the gradient will curve away as time rolls by.
