I use Organic Maps as my standard maps app which is an Open Street Map based app. I find it’s pretty good but can be a bit lost around heavy traffic. Cycling is definitely an option. I’ve not seen “collaborative lists” in the software but I’ll take a look. I sometimes use the google maps web service because for some reason Open Street Maps doesn’t display suburb when searching for a location and it can be really confusing to figure our which one you are looking for.

Another Zen user chiming in to say, all the other ones seem confusing and cluttered now.
