I figured I'd make a topic for people to suggest what they'd like to see in the map Editor.
Users can post their suggestions here and i'll make a list of it, attaching imagery in links for as inspiration.
Note, once again, that these are suggestions, and the Devs will have to decide wheter to add them or not.

Barricaded On/Off Ramps
Pretty self explainatory. On and off ramps would be attached on the outersides of the trackpieces so that you can keep a modular middle section (Change the amount of lanes) These would be blocked of by an (in)visible barrier, like traffic cones / concrete barriers / Variable Message Signs with arrows on them.
Bridges
Probably planned already since I've seen progress on water, but for Sunset city I'd love to see something similar to the Bay Bridge
(Smart) Support Pillars
If possible, there could be a system that recognizes when a road piece is under another road piece (like in loops and stacked highway segments) and make the pillars protrude to the outer sides of the highways.
Decorational/Non Functional Roads
These would be attached to the On/Off ramps, these road parts aren't part of the race track, but add some aesthetic, and make it more like an actual Highway netword instead of a looped section.
These pieces could act as "The opposite-bound" side of the highway. And they could possibly support dummy-traffic that follows an AI path.
Tunnels
Another one that's probably quite obvious. But kinda of tricky to implement since there is a lack of elevation in some maps. Here is some inspiration for what the tunnels could look like though.
Highway / Speed Limit / Warning Signs
Already Implemented. But maybe more additions. to support landmarks. Like Sunset City Bridge, Route 83 Tunnel, Road Closure Ahead (forcing players onto an off ramp) and other variations on these kind of things.
Further, signs suited for roads with less lanes, and signs that can be put on the above mentioned decorational pieces would be nice.
Dummy-AI Traffic
Like the train: This could be the current ingame cars, or new additions that are unplayable. (SUV, LCV, Large Truck, MPV Taxi, Police Car etc.) These would ride on the Decorational roadpieces (if toggled) at the speedlimit (sunset city has a higher speed limit, because it's a highway, then for example the island-like map)
Decoration Suggestions
Here are some suggestions that would make the map feel more alive.
- Wind Turbines
- Airplane Smoke Trails
- Power Lines (Large and small ones)
- Contstruction cranes (For semi-contstructed building decorations)
- Semi-constructed Buildings
- A Stadium Like Building
- Spotlights
- Pine Trees
- Waterfalls
- Roadworks / Construction items to narrow down the road.
- An Airport map with airplanes flying overhead. (Airplanes, Flight Control Tower, Hangars, Runway lights. (Think about the airport maps of NFSU2)
- Toll Booths
More to come, including a drawn map of a re-imagined Sunset City (one that would have these features) I'll add other people's suggestions to the main post.
Let me know what you think
