When it comes down to mass production, you'll never know how low it could be priced. I concede that $3000 is a big lot of money. But give it some time, see how it drops, wipe a zero of that price, and now make comparisons. The biggest part of the price is due to I&D expenses. If this toy/tool has a market niche, I think it will come down to a price suitable to that niche.
Of course, provided it works as advised.
Oh, and the average Spaniard walking speed is nowhere near 10km./h. I would leave it between 5 and 6. OK, if it's a bar near, 7 on the way-in, 0 on the opposite.
