The streetpass ads show it working between pedesrians and cyclists, though I've never had a hit when I'm cycling. Although that probably doesn't mean anything as I've never even got a hit sitting at the lights.|
Hmm, on second thoughts I did get a hit on my bike when I was in Brighton. It probably helps that the cycle path goes through the middle of the pavement where the promenade is there.
Cubby didn't know how to turn off sigs!
