Hi

I use mkgmap/Garmin a lot for road routing and driving and frequently find cases where
1/ exit roads cause pop-ups telling me to turn to stay on the main road.
2/ an obvious turn is needed to stay on the same road and no pop-up is generated.

These were some of problems that --adjust-turn-headings with code in
RouteNode.java::tweezeArcs() was designed to solve.

I'd like to have a go at reinstating it and tweaking it a bit to see if I can overcome some of the problems mentioned in some of the threads, eg

http://gis.19327.n8.nabble.com/What-is-the-idea-behind-adjust-turn-headings-td5851885.html

before it was removed in r3649.

I'm considering putting the code in imgfmt/app/net/AngleChecker.java

Case 2/ can have further complications because OSM doesn't provide information when you have to give way as you turn to stay on the same road.

Another pop-up I'd like to see is the minor road you wish to stay on is intersected by a more major road and you have to give way. Does anyone know if there is any way of triggering this?
