It always cracks me up when people take nav technology too literally. It's a supplement to your freakin' brain, not a replacement for it.
Waze (and all other nav programs I've experienced) tells you well in advance that your destination is coming up. Do you really need your hand held all the way to the front door?
Similarly, common sense should tell you that the entrance to a business isn't down a back alley.
Navigating to my local rail station, Waze tries to take me to the wrong side of the tracks. Sure it's the station (Waze is right) but it doesn't know where I need to be. So -- duh -- I just ignore the directions when I'm a block away and drive to where I need to be. Simple observation tells me that I need to cross over.
For me, Waze is the killer app and justifies owning a smart phone all by itself, for the traffic routing and police warnings. I prefer alternate interfaces, though; I don't like having to parse a map view while also riding/driving. On the bike, when I actually need to navigate somewhere (rare), I use CoPilot's "safety view" and have Waze running in the background for police and hazard alerts.
Re "motorcycle mode," if I read the description correctly there's a crowdsourcing element to it. Routing is based on routes that other motorcyclists take. That suggests a tweak to the algorithm. It also suggests that out of the box, there won't be much difference because the data isn't there yet.
