The Briton, world champion with Brawn GP in 2009, said last season he would consider his future in the sport if such blatant manipulation was allowed.
He spoke out again on Friday against teams favouring one driver over the other, as Ferrari did last season when they triggered an outcry for telling Brazilian Felipe Massa to move over and let Spanish team-mate Fernando Alonso win in Germany.
However, Button said he did not expect a sudden outbreak and was looking forward to a great season of racing with five champions on the starting grid.
“I don't think it (team orders from an early stage of the season) will happen, I really don't,” he said. “I think they (teams) will realise that two drivers are better than one. For setting a car up, you need two experienced drivers. If you are putting all your eggs in one basket, the other driver's not going to feel like giving you feedback, is he?
“He's not going to feel like pushing the car to the limit. He's not going to qualify well and he's not going to race well,” added Button.
“If I had a team, I would have both drivers having a fair shot at it because they are going to push each other hard.”
Button said he saw the rule change as more of a clarification by the International Automobile Federation (FIA) to reduce the risk of the championship being decided in court rather than on the racetrack, and as an admission that such orders could not be policed effectively.
“I hope that drivers are allowed to race fairly,” he declared. “You do all this hard work of getting to Formula One and fighting your way through the lower ranks and you arrive and you should be given fair treatment,” added the 31-year-old.
