The map and text in the post are a bit misleading as the map shows the data from 2001 to 2024 and the text only talks about the average for 2024

I agree for the graphic but I think the reason for the solid color is that it was never intended as an image but just as an interactive map on the website. You can zoom very far in and see every (half transparent) point. Filtering for all, just driver / passenger death and pedestrian / bike / other deaths and choosing the year interval (2001-2024 as default) are nice extras

Reminds me of the manhwa / webtoons “Surviving the game as a barbarian”
