Cruise Control problems of the 2003 Mercedes Benz 320

I am concerned that the arm for the crusie control is too close to the turn signal arm. Several times a day I find that my hand (albeit a small hand) accidentally hits the cruise control lever instead of the turn signal - especially when signalling left. This activates the cruise control at a time when you are usually getting ready to slow down for a turn. I understand that braking will turn off the cruise automatically, but it is still an incovenience and could potentially be dangerous. I contacted Mercedes Benz and they said that the cars are all put through many, many tests and this problem didn't surface. A solution would be too shorten the length of the cruise handle or angle it more toward the dash. Possibly this would allow fewer mistakes.
