How about quality of data, I mean, for instance if you have to backtrack 
in a road, will you have to delete the log and restart all over? How 
about connecting two pieces of log? What about changing direction 90º; 
if walking (or even biking or car), in reality you are not doing 90º, 
will be doing a diagonal or a curve, but one wants to provide to OSM a 
90º road connection.

Essentially I'm trying to understand how burdensome (or not) it can 
become for a simple sightseeing to also do tracking.
