I’ve got the Peak Design Qi2 wireless charging stand on my desk. It really is a very well-designed piece of equipment. I’ve been a fan of Shokz for a while.

The efficiency depends on the query size relative to the data distribution. A small query in a sparse region prunes almost everything. A query that covers the whole space prunes nothing (because every node overlaps), degenerating to a brute-force scan. The quadtree gives you the most benefit when your queries are spatially local, which is exactly the common case for map applications, game physics, and spatial databases.
There’s already a dedicated F1 channel in the Apple TV app, which is where you’ll stream races live when the time comes. You can also watch practice sessions, sprint races and both pre- and post-race coverage. Apple offers a number of additional F1 videos there (I’d recommend watching the one on the new rules) and you’ll be able to stream the latest season of Drive To Survive on Apple TV as well.
