Streets meeting at less than 46 degrees

When streets meet at less than 46° the default turn instruction may not end up being true to life. The instruction may be "stay to the left/right" when drivers would consider it a turn, or "exit left/right" when the driver would consider it a "stay" or "turn". If a junction's angle of <46° corresponds to the natural path of the driver’s path approaching the junction, then a TIO for turn left/right should be used. If the angle is adjusted to >46° and < 170° then the Waze app will produce a "turn" instruction by default.

There is no need to search for and adjust intersections currently using doglegs or microdoglegs (the previous best-practice approach to correcting turn instructions). They can be replaced if the intersection needs to be edited for some other reason. Any Intersection using a "stub to nowhere" or "fake alternate name" to control turn instructions can be corrected to reflect reality and use Turn Instruction Override to control the instruction.

If the intersection has a departure angle of < 20°, it may be best to adjust this to something between 20° and 25° for two reasons: 1) to make it easier to select the correct arrow in the Waze app when reporting road closures; 2) to make it easier for senior editors working mobile to select the correct segment for uplock or downlock
