YouTuber euverus modded Cities: Skylines to demonstrate how 30 different types of intersections have dramatically different amounts of traffic flow. A four-way intersection with no traffic lights gets a flow of 191 vehicles per minute, where a stack interchange can handle 1099 vehicles in the same time frame.
The mods used, Traffic Manager: President Edition and Network Extensions 2, are both available for free on Steam.
The big surprise for me was the roundabout, because we rarely have them in the Midwest or the West Coast. They seemed like a lot of extra space needed for an incremental benefit, but it appears they can be more efficient and safer, even weird ones.

Most of us are pretty good at wrapping a cube or cuboid box, but this handy video shows how to wrap a bunch of weird shapes, including pyramids, cylinders, and those annoying cardboard-backed blister packs for things like tools and action figures.
I needed to wrap a popcorn tin the other day, and this was very handy. It looked way better than my gifts usually do! And as for opening the package itself, that's another matter.
