This is great stuff, looking forward to see what kinds of things can be done to add detail on layouts.
I hope i'm not too late to suggest anything, but Elmo's suggestion of stacked armco wall is something i'd love to see. You can stack the current armcos but it would take 3 object spots for 1 "full object", and if you want to hide the legs of the lowest armco you risk catching the tyre with the lowest armco's top part of the hitbox (the tyre tread can "jump" from asphalt to on top of it if the armco is low enough). Having coloured options of the armco would be cool as well, for example original steel, red/white variant and perhaps yellow or white with blue or black.
Also adding to the armco, would it be possible to have a fence or a fence wall as well? Would only need to be a rectangle with a texture and collision, like the ones in the current tracks we got.
Layout pitlanes could be made more detailed by having a tent like in the example pic above but without the side walls. Of course it doesn't matter that much but it's a small bit of immersion.
Last but not least, a larger ad-banner similar in looks to Westhill's ones but a lot smaller in size would spice up layouts a lot as well and has a lot of use, especially if it would have it's own texture, or a set of them, like the smaller banner boards that are in the game currently. One example of a decent sized ad board would be 2 posts above in the Tsukuba picture.
