Actually, I think I found it: https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=1285201733

thanks @tbg10101

Biffa is using that mod, but also the BPL, or Big Parking Lot mod suite, which I actually had to pull out of a previous video way back from the TeaVille series in which Biffa discussed some of the mods he used for managing parking:

I also found a couple parking garage assets in the workshop that may be appreciated:

Thanks guys, that's so helpful!

When I use the parking lot roads mod, as tbg linked above, the parking lot connects to the road by a thin strip with pavement either side, instead of using the full width of the parking lot like it does in Biffa's videos. Is this from a different mod?

When you connect the parking lot road directly to another road, it will connect using the full width.

When you connect the parking lot road to another road using the two-way drive, that's when you get the thin strip and pavement.

It looks like this might be the actual asset used in the videos https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2165419951&searchtext=parking
