We've done it now about a week ago. They picked us up at the hotel in Bam. Before we've left BAm the escort allready changed 4 times. And then again to Zahedan the same thing. Was not so bad after all. Actually almost never allowed us to stop. The first policecar was stopping while the one that took over was taking off. Some parts they 'lost' us and they did not seem to mind. It went so fast that we decided not to stop in Zahedan but cross the border the same day. Arriving in Taftan at sunset we did not wanted to drive at night so slept in the 'hotel' next to the customs office (could not find an other). That was bad!!!! Taftan - Quetta, about the same experiences as Toukakoukan. Although we've had some escorts once in a while.
We found the road from Quetta to Multan much worse. It's about 600km from which there is a part 65 km unpaved (among more). Then as we saw that we would not going to make it before sunset and wanted to stay at Dera Ghazi Khan the police told us that we were not allowed to. At a certain point after that they gave us an police escort, which was oke considering it made driving in the dark much easier. In Multan we wanted to leave without an escort, but they stood waiting for us outside the hotel. So we've had an escort for a great part of the way from Multan to Lahore again. Although we rather rode without it, it did had it advantages and the policeofficers were very friendly.
Hope this is of some use.

Marcel
