This is likely laziness more than malice, but... why are busses connected to the internet?

In China, most of buses in first-tier cities are connected to the internet to report their location and status. This allows you to check the approximate location of the next bus and a relatively accurate arrival time on a map app. It's especially useful in bad weather or traffic congestion , as you don't have to wait in heavy rain or strong winds for a bus with an uncertain arrival time.

Real time position tracking, CCTV streaming/archiving, automatic diagnostics logging, there's many reasons for a modern bus to have wireless data connections and I'd be shocked if most modern buses in the US and Europe don't already have such systems (i know here in Chicago the CCTV feeds can be viewed remotely by staff and most buses have their real time position available via public REST API, though i don't know what tech the buses themselves use to transmit that data)
