Roads and highways.

So I have recently been doing some remodelling and deep in my inventory I found the old krusty land highways.
These seem to be absolutely useless! They are an odd sized, have no corners and don't link to normal roads.
Also if you place down basic roads side by side you with a long divide down the middle it looks good......... That is until you move a tree or a building or anything. All the roads link on the corners giving lots of little roundabouts.
With the new car parking lot that just dropped in the summer games update this looks like a great way to add new road pieces.
What would I like to see?
1.Get rid of highway pieces (or make them sellable).
2.make new road pieces. 1 side with pavement (path/walkway) , 2 adjacent sides with pavement and 2 opposite sides with pavement.
3.make the pavement the only live part of the road. So you can place any item on the road.
4.paths. Make it so I can place all items on all paths. (this come from trying to place both itchy and scratchy balloons on krusty land paths.

I would love so see other people's views on these points.
