Google Describes Wi-Fi Sniffing In Pending Patent

After mistakenly saying that it did not collect Wi-Fi payload data, Google had to reverse itself, saying, 'it's now clear that we have been mistakenly collecting samples of payload data from open (i.e. non-password-protected) Wi-Fi networks.'

But, as Seinfeld might ask, then what's the deal with the pending Google patent that describes capturing wireless data packets by operating a device - which 'may be placed in a vehicle' - in a 'sniffer' or 'monitor' mode and analyzing them on a server?
