https://www.theguardian.com/uk-news/2016/dec/31/boris-bus-london-transport-sadiq-khan-end I'm not sure whether this was a good move by the new mayor. On one hand the new routemaster has an outdated and polluting diesel electric system, on the other hand it is a nice looking bus with comfortable lighting which is nice to see. I do think that with the amount spent in developing the bus, it is a terrible time to pull out of the deal at this stage - all it means is taxpayers getting a worse deal. The whole economy of the new routemaster was about the bulk quantity that would bring down the initial development costs. As for pollution, instead of going in and scrapping the entire bus design and platform, I think it is shortsighted of Khan to not have utilised this and worked with Wirghtbus to manufacture buses with new more efficient full battery power rather than diesel electric. It seems like a huge waste to develop this product then drop it instead of working on it to be more efficient.
