The entire industry collapsed, but he worked on https://framevr.io/ which was exactly the type of software that people flocked to during COVID. After people were able to go home again, many of these companies tried to pivot to the metaverse in hopes of jot throwing out their product entirely, unsuccessfully it seems.
Conceptually, it’s not terrible. The product isn’t as much of scam as you might think it is based on the metaverse tag.
I always thought these markings were made by machines, until I saw some people draw them by hand. Turns out, you can make near perfect road markings with a movable can of paint. If you use GPS to trace out your track, you can just fill them by hand.
As for construction, here’s a timelapse of making one using stone tiles: https://youtu.be/gXiOt-9WCag
Here’s one made of asphalt: https://youtu.be/DORBEGYVgYE Note the pre-poured blocks of concrete in the center, which likely help the round shape.
In this video you can see the imperfect temporary road markings for a short moment: https://youtu.be/SV2vSL_hiA0
This video showcases a different style of roundabout that makes two-lane roundabouts a bit easier. Note the two round, concentric lanes separated by concrete barriers: https://youtu.be/iRclLOgN-xw
This video showcases the manual driving work done to make the round roads: https://youtu.be/KCQv24BkI6Y This is a four lane roundabout. The video also shows how the line markings are applied (by a spout, in a car).
This video shows a prefab concrete roundabout installed over a weekend. All they needed to do was prepare the soil, lay down the blocks and paint the lines: https://youtu.be/J-BZWfbygkc
This video shows how the center concrete slabs can be laid on location using a specialised machine: https://youtu.be/J2g0JZzqbAs
I’m not sure if this tech is applied, but farmers use millimeter precision GPS to efficiently farm their soil. The GPS receiver itself costs a couple of grand, but making a car in a closed-off road drive in a perfect circle is hardly a technical challenge these days. That said, these people can probably do it by hand and you wouldn’t notice the difference.
