I had a good idea today. I'm responsible for our motorcycles program: we bought some motorcycles, and we're going to let some independent drivers rent them from us. They're also required to provide one free return trip to a One Acre Fund field manager each day.

Somebody else had the idea and did the profitability analysis. I'm not in love with it, but since it's mine now, I have to figure out whether the original rationale holds: is it reducing transportation costs for field managers?

Problem: how to get good data on usage? Drivers don't want to give free rides, but will probably say "of course I gave a field manager a ride today" anyway.

And for field managers ... frankly it's not that convenient. Each location only has a couple motorcycles, and drivers might be busy or have already given their free ride that day. But the field managers know they're supposed to use them, so they might just say "of course I used the One Acre motorcycle."

Solution: give vouchers, with random serial numbers, to the field managers. They give them to the drivers, and the drivers write their names on them and give them to One Acre when they're submitting fees. Barring a motodriver-field manager conspiracy, we'll know exactly how much field managers are using the bikes.
