Doing a quick Google search, it looks like scooters would cost $1500-$2000 retail, but you could get one on sale (or haggle down) for maybe $1000. Add in taxes and helmet and stuff, call it $1200 each.
Might also want to add in an extra $50/month stipend (on top of the +$100 general raise I was going to add when the restaurant is active) for those with mopeds, for gas costs. That would cover about 1000 miles per month of driving, which is probably overkill.
I would attach the cost of gas to general upkeep rather than the stipend. Since much of your gear is used across multiple people anyways.
Your estimation of 1200 per moped and 50/month upkeep sounds reasonable though for those.
While that fuel cost does seem high, the thing about mopeds and other expensive vehicles is that we should probably also factor maintenance and replacement cost into the upkeep. Let's say a moped will last say 10 years before it needs to be replaced (usually longer, but we're including maintenance too); that means an annual amortized replacement cost of $120, or $10 a month. That, along with fuel and other parts/labor costs, adds up to our $50 a month quite nicely.
That said, IMO it'll be worth it. Sure, your average meguca could pedal faster than a moped, but it'd certainly be less tiring, not to mention draw less attention, to be on the moped than on bikes. We could probably get away with juicing our delivery business's profits a little, too.
Even longer-term, we should consider full-on motorcycles (say maybe $10,000 per bike and $100 per month upkeep, again accounting for fuel+maintenance+replacement costs) for the rural and nomadic regions. Those should help negate some of the range penalties associated with rural and nomadic hunting.
The nomadic region in particular interests me, as that strikes me as the region most cruel to meguca, and yet the one place that we can't really as of yet bring our organizational advantages to bear. Right now I'm imagining a pair of vets--a hunter and a clairvoyant--being paired up on a motorcycle, given 6 units of cubes as an emergency stash, a decent living stipend and two sets of armor to go with their cell phones, and sent on a month-long ranging expedition through the nomadic region. A pair like that be able to at the very least be able to draw a slight grief cube surplus, and even if they can't we'll have pre-supplied them with enough grief cubes to tide them over. Another possible benefit is that any nomad meguca they meet along the way can be potentially recruited fairly easily, since most nomads are probably living hand-to-mouth and haven't had a decent place to live or a solid source on their next meal/despair ration since they contracted, and being given a couple hundred bucks, a carton of grief cubes, and the promise of a warm bed and a shower should win 90% of them over.
There's an actual date given? I never saw one.
I don't think there is, but the technology advance is indicative. Technologies used by teenage girls, such as cell phones, laptops, and tech seen in schools, have advanced significantly, but things used only by adults--cars, for example--remain about where they are today. That tells me that we're looking at an alternative modern day, where wishes made by some girls have advanced the tech available
to them, while the fundamental tech level is similar to what we have now.
Besides, it makes sense. Especially in a nation like Japan, where academic achievement is so very important to young people, I'd expect a lot of Wishes to be something along the lines of "I wish I was smarter/my school could teach better/learning was easier"
