I don't think it will SUDDENLY change the lights either.. I see it as more of a system like the infrared one currently used by emergency vehicles.
I brought up the piggy backing thing for wifi-enabled buses because *that* is what is currently standardized and in wide-use across the world.. many transit authorities allow passengers to use the network, but with a ton of disclaimers since they get hacked so often.
I see nothing on
Welcome | Modern Transit Project in Oklahoma City that says we'll be moving to the currently implemented wifi-enabled buses, just that the lights can be controlled via wifi.
Which I think is a bad idea, considering how easy it is to intercept, crack and manipulate wifi. Especially when any script-kiddie can just sit down near a traffic light and collect packets all day long..
