I thought the article was just saying that the cars will broadcast their speed. In this way cars will know if they are slowing down ahead of them, and it will be built in, so it won't be easily hackable like you described.
Things like this could possibly save Millons of hours a year. Quite powerful.
Ya I know. I meant hacked as in regular drivers randomly broadcasting signals saying traffic jam ahead. Obviously it can be hacked, but it will have to be a lot more sophisticated then that.
