I'd concur, this and more a leaning towards smaller cars, again due to population densities and proximity to resources (shops etc). Which may also explain less pickup trucks, which would be more useful in a more spread out resource/population as would allow large load transportation. Which given distance and time, would make sense. Which equally allows any bulk material resource supplier more able to provide delivery as cost effective for them, again due to population density. After all, if you have a spread out customer base of equal numbers then it may make more sense to not offer delivery, leave that to the customer and offset that with offering cheaper product price. Then any delivery option on offer will be custom and more expensive as would be farmed out, but still an option. So the tendency to go for a pickup truck, increases for the populus in more spread out area's.

But equally can't overlook the government incentives offered in many European countries and those have been IMHO pretty aggressive, making EV's a very tempting option for consumers.

Though, gas/petrol/diesel is more expensive in Europe and does not have the governmental subsidies many other countries offer and is equally very taxed. Again making EV's, very much cost effective for so many. Some places even offer free charging, if not subsidised charging.

So factoring is the demand for smaller vehicles needing to go shorter distances and those incentives/subsidies, then you can see why EV's in Europe garnering much traction.

I almost forgot congestion charges, EV's avoid those and they can add up in some cities/area's (thinking London for example).
