I'd love if Waze could be put into motorcycle route mode to give you an optimal tour route. Yes, you can avoid 'freeways' (better known as highways where I live) but that seems to cause Waze to put you in stop and go traffic through cities with traffic lights and stop signs. Not fun.
It also would be nice to be able to give/get reports of additional hazards that are important for bikers, such as loose gravel, low shoulders, and uneven surfaces, for example.
I love Waze and often use it in my car, but for my motorcycle, because of the above, I tend to use other apps.
