I didn't think it was nice of them to tell another team they needed to change money, but the cameras didn't capture it so who knows how it went down. Maybe they wre speculating out loud. Or maybe they're just showing they can really play competitively, borderline dirty.
I prefer the whole race be run "clean" but with the addition of the new yield feature, they are incorporating slowing down other teams right into the game. So I can see how testing another team's gullibility fits into that mindset.
