Big Brother Buses

Since I started cycling to work, I don't go on buses very often, because I don't have a travelcard.

Last time I went on a bendy bus, I was amazed by what I heard: non-stop announcements, telling you to watch out for unattended baggage, and to report any suspicious looking people.

These announcements are common on the Tube; however it's the sheer quantity of these announcements that amazed me. It seemed like there was about 30 seconds between each one - making it very difficult to have a conversation.

Does this really help the war on terrr? [sic]
