Good work
The set of categories of vehicle types is missing "pickup truck". Some limited-production electric pickups have been built (for many years), and more are coming. Since this is a functionally distinct category, it should be available.
It could use a "select all" feature for manufacturers, so it would be practical to select all then exclude specific manufacturers; that makes it easier to compare one brand to the rest of the world.
The regional versions (listed under "New features coming soon") will be good. If someone is actually shopping (not just interested in the technology), local availability is crucial. This could be a challenge, though: although there are several EVs which are theoretically available in Canada, only the Nissan Leaf and the various Teslas can be actually purchased in the province of Alberta. For instance, the Chevrolet Bolt is common in Ontario, but Chevrolet dealer sales staff here have never seen one, and some have never even heard of it.
