The tech seems really cool, but the road showed in the examples is not any less insane, like, why?

Their animated gif at the very end of their own tech seems very sane?

I wish they'd actually shown more/talked about it though.

Will share more soon. I have some more recordings of it on x https://x.com/SandboxSpirit if you're interested.

That's the point? Even though they are complex, the improved roads all use circular arcs which guarantee a baseline of good drivability.
