-equip all cabs with trip speedometers and a voice memo-taking device.
-every time someone exits their cab, drivers make a memo of the pickup location, dropoff point, time, distance, fares collected, and any incidents that occurred.
-manager collects memo devices regularly to compile and review data.
I'm going to have to start doing this myself. As a driver I would be interested in my average distance, speed, fare, and so forth because those are questions my passengers ask me sometimes and it would be great to be able to tell them accurately. Maybe even mount the speedometer where passengers can read it! (I get to bomb down a lot of steep hills so it'd be fun to see what kind of top speeds we're hitting)
Anyway, it would not take too much time away from a busy pedi-cabber to simply punch a few buttons on the recorder, and then a few on the speedometer and read off and recount the info for the last ride. Maybe 10 seconds between rides, and if the recorder is mounted on the handlebar, one could even get moving while in the process of logging data.
I'm thinking too of the possibilities of leaving the recorder on whenever passengers are aboard, either for evidence in resolving claims or maybe for the more whimsical purpose of documenting "pedicab confessionals" that passengers might be willing to give...
