It isn't an abuse currently. I meant allowing a censor controlled by a person to provide input into a stop light is troublesome. Just like people who get ahold of the light emergency vehicles can use in certain metro areas, having another way to try and hack the light is likely to cause problems.
I think he's referring to this line in the article: "Even better, if there's no oncoming traffic, your Audi can make the light turn green." I'm pointing out that there are lights that already do this for regular cars.
