I would LOVE for waze to have multiple options for routes. For instance :
Standard options:
- shortest distance
- shortest time
Standard avoids :
- avoid toll roads
- avoid highways

New ones:
- least turns
- least traffic lights ;

New avoiding routes:
- avoid construction routes
- avoid one lane streets
- avoid streets with traffic moving slower than

All of these should be able to mix and match and specify further details. For instance it would be great if it showed option to list trips within X percent of time to shortest time trip. It can display stats for these: ex: 25 turns, 10 Street lights, 2 one lane roads, etc etc
