Create lane assistance like Tom Tom.
I have iPhone 5 with iOS 6 and as its a bigger screen and faster chip I think waze should create lane assist like Tom toms. This would be big but could be completed by wazers on editor for points, it would soon catch up. Lane assist can tell you which lane to use for a direction.
Very useful. even google navigation has it so this should be a breeze since you are part of Alphabet.
This is very useful in older cities with complex turn-offs and congested streets like NY, Boston, Philadelphia, Washington DC, etc.
This is very usefull. The OpenScreetMaps project has this information and the OsmAnd navigator use it to indicate what lane do you neet to stay.
