For the bikes, since Googlers think it's fine to leave them at trolley stops, they've started putting GPS trackers on them, powered by generator hubs. I'm guessing this won't last given that generator hubs are valuable. Better to have people stealing them to ride than stealing them to sell or recycle the hubs.
@seanl What's annoying is that dynamo hubs are a luxury good in the US.
Actually, a lot of gear specifically designed for transportational cycling is cheap and common in Europe, but expensive luxury goods here...
