I tested it out with my typical work commute and the routing seemed pretty reasonable actually, beyond unprotected straights and left turns on major arteries that just aren't going to be easy to do. My issues are of course the osm layer view has a lot of seemingly useless information that I can't make any sense of. Look at the region around Beverly Blvd and Silverlake Blvd in Los Angeles: What is all that red stuff randomly on roads and alleyways supposed to represent? It's also on the stands in the hollywood bowl. Bike lanes are also not demarked on here, although weird things like the 'official' route of route 66 through LA are demarked clear as day although I'm not sure why anyone would ever need that piece of information. There's also a dotted purple line on some streets that I'm not sure what it could possibly represent, because its kinda like the red lines just randomly applied without any significance seemingly. Another issue seems to be that I can't type an address at all, I need to zoom in and choose it with the mouse. Good luck with the project, hope my feedback helps some.
