Since you started teasing this tool a while ago, it's occurred to me that the old paradigm of "build-bulldoze-rebuild" really isn't ideal or sustainable for games with freeform roads. The ubiquity of the "Move-It" mods for both Cities Skylines games (as well as related things like node controller) reinforces this idea, as does my experiences with the occasional finickiness of the road tools in CS1 and SimCity 2013. It's just not a good user experience needing to completely redo something every time you want to tweak it, or when you slightly misclick, or when the auto-generated intersection turns out screwy.

100% agree. When I was building an intersection for 2 hours and then realized I needed to move something because the angle wasn't right, I almost uninstalled the game. That's why I think this is one of the most important tools in the game.

Also, when you're designing, it's like blueprinting. You need to have the tools to design quickly and efficiently. Once we get to the city builder stage, and you actually design, confirm, and build the intersection, that's when making additional changes should affect the gameplay, but not in a punishing way that requires more grind, but like paying more money to reconstruct stuff you designed wrong and it affecting your popularity as a mayor who wastes time and money redoing something they just approved. Damn I am really looking forward to the second game.

I had been curious about how you'd handle this kind of freedom in the context of the city builder, since it'd be a bit unrealistic/overpowered if you could just freely drag things around all over the place. Having a separate design stage before you confirm the final construction would make a lot sense for that, so you can get everything right and do most of the tweaking then, and of course still being able to tweak things afterwards, but at some cost..

Lane change is now finally smooth, also the distance it takes to change a lane is proportional to vehicle speed, so with low speeds lane changes are going to be short, while with highway speeds they might take up to a couple hundred meters.

These are procedural, so most things can be generated, all we need is an algorithm that will set the values. We could easily add for example lane sorting signs

All vehicles will keep right (outside of cities), not just trucks

Left lanes should be used for overtaking

If agent's desired speed is higher than of the vehicle ahead, they will swap lanes, unless they need to stay in the lane due to navigation reasons

Speeds and accelerations will be way more realistic compared to csl1 because we don't need to simulate one day in 20 minutes

I'm implementing some driver behaviours, at this point there's a gaussian distribution of stats, most drivers will average around the speed limit, others will go faster, others will go slower. The curve will be editable via config file. Most drivers will then be affected by road and its surroundings - when a lane is narrow, they will go slower than the speed limit, down to 20km/k when there's very little clearance on both sides (shoulders add clearance, not just lane width). Then if lanes are too wide, drivers who break the speed limit will have tendency to speed more. And lastly if there are trees or other high objects placed very close to the lane, this will have the opposite effect, and speeders will tend to slow down. It's just a very basic implementation so we have something ready for EA and it can be expanded upon later.

[...] vehicles will slow down when the road curves, and all drivers will have their own internal max speed, so when you recreate the autobahn, most people will still drive relatively normal

Every vehicle has 3 dimensions + weight + turning radius + max slope + max speed

There will be a demo for everyone to try on all supported platforms

Also every mechanic will be unlocked incl. the full tutorial
