"ok glass, how fast are we going?"
Really? You want to ask Google rather than the driver?
How far to the top of this escalator? Can't we just stand on one for 30 seconds without having to perform some micro-action? And anyway, the app would just be showing some "failed to connect" message here (plus 3 minutes for an escalator to move 197 feet (about 65 metres for those of us in the current century), really?)
I'd halve the number of shots in this pages, but make them the really good ones, the message is pretty diluted, otherwise.
