I found this description on a website describing another Chinese city, but it applies perfectly to driving in Lhasa, or anywhere else in China for that matter:
The rule of the road is "me first," regardless of signs, traffic lights, road markings, safety considerations, or common sense, unless someone with an ability to fine or demand a bribe is watching. In general, the bigger your vehicle, the more authority you have. Maximum selfishness in the face of common sense characterizes driving in general, and there is no maneuver so ludicrous, unreasonable, or unexpected that someone will not attempt it. Residents have time to adapt -- visitors do not. Our strong advice is to forget it, and take a taxi.
This is also my advice, but there's little to worry about since foreigners can't have cars or motorbikes. Instead, what should be done is cultivation of the "close the eyes and pray your driver is not still drunk" method. On my first ride into town from the train station, our driver turned onto one of those four lane highways with the cement and pretty plant dividers between the opposing two lanes of traffic. This is not strange at all, usually, one crosses the intersection to the other side of the road and turns left into the proper lane. However, our driver saw that it would be far faster to turn directly left into two lanes of oncoming traffic, then "sneak" back across the divider into his proper lane only when a larger vehicle was coming straight at us, provided of course it waited until there was an opening in the cement divider. I thought he was just crazy, but this is actually a normal policy for drivers in China. I have actually witnessed a Chinese driver in a fancy new SUV purposely bump a police man, who was on foot, until he moved out of the way and unhooked a rope that was blocking traffic due to construction on the street. Our driver had the same kind of SUV, but he is Tibetan, so we drove the fifteen minutes around the construction. I didn't catch the red character on the Chinese man's license plate, but the police didn't seem to want to do much about being pushed around so I would guess that the driver had some kind of special hat on or something.
The other day, I saw a taxi driver wait until the light was red, and then proceed into the busy intersection just to the right of the Potala. All this crazy driving wouldn't be quite so bad if the pedestrians and bicyclists weren't operating under what appears to be the same insanity principle.
In any case, here are some more pictures of trips around Lhasa. Our valiant leader, Lhakpa, took us to see the Potala on a Friday, but there are few pictures because none are allowed to be taken inside.

The foreign students entering the museum of the "Old Palace". Here Lhakpa begins his descriptions and dissertations on the sights and sounds of Lhasa's most famous landmark.











The walls are several meters thick in places:

Seriously though, the tops of walls in the Potala exhibit one of the unique facets of Tibetan architecture, the Benma wall, which are made of, you guessed it, Benma grass. The grass is bundled very tightly after being dried and then cut to length for building the tops of houses and monasteries, apparently because they never heard the story of the three little pigs. No, actually, it is used to build instead of stone so that they can build higher without the weight of the roof causing architectural disaster. The Benma grass is painted in a sort of burnt reddish color so as to provide "a decorative role by offering a strong color contrast with the dominant white, resulting in a good visual aesthetic feeling." One should note that the Benma walls reflect the strict class system that prevailed in Tibet, prior to liberation. Of course, the great magazine article writer Cedog, whom we have to thank for his insight into Benma architecture, is of the opinion that the architecture originated with the common people, but developed into a class defining symbol only later in history.

...Really, it's quite good actually. I tasted some, just like tsampa...
no, not really. I heard someone got sick recently from eating it.
No, just kidding, it really is edible. I had it with rice crispies once.
Lhakpa said it was edible...


Now, if you would please turn your serious scholarly attention to the murals:














More on insane people and other sights around Lhasa soon...
