As I understand it Dynamic Lane Selection changes the pathfinding of vehicles, specifically the lane selection. So unchecking that box should have CS run on vanilla lane selection rules right?

In vanilla CS adding a right off-ramp to a highway makes cims avoid the right lane and adding a left off-ramp to a highway makes them avoid the left lane. However with TM active but DLS unchecked, cims respond to left off-ramps by everybody using the left lane exclusively instead of everybody avoiding it.

With regular roads, left turns also mess up the lane selection. Normally a 6-lane one-way road can be split between 3 2-lane one-way roads. Cims will get into either lane going their direction (depending on which lane they need to be in later down the road). However with TM active and DLS unchecked they will only take 1 of the 2.

Is there a way to use TM features with vanilla AI? Is this a bug? Is TM not meant to be played without DLS? If the last thing is true, can you add a warning message to the options menu?
