> Here (Netherlands) the overhead matrix highway signs indicate lower (legal!) maximum speeds the nearer you get to a traffic jam. Same here in Germany. I know this from Berlin's inner highway which has automatic traffic signs. Sometimes just a jam warning sign appears, sometimes the maximum speed is reduced, sometimes both at once. > On a related note, i propose using telephones for talking. I often had a similar thought: What if I could talk to the people in the cars next to me? What are they thinking? Why do they act the way they do? However, I quickly abandoned that thought. The traffic is moving very fast, decisions must be made very quickly. There's no time for a quick chat with all the drivers around me. It would be an additional distraction that would probably do more harm than good.
