You cant do science by driving. And they have a perfectly good view of Gusev from orbit - a far better view than a rover could ever give them.

The rover can drive with 5 wheels perfectly well - so that's not a problem either.

It's very VERY tempting to say "screw the science, lets go sight seing" - but that would be an insult to each and every one of the american tax payers who've paid for these things. They already have more than their moneys worth, but with what life the rovers have left they should continue to do the carefull and systematic science that they have done for the last 200 sols. The story of Gusev will be told by studying the stratigraphy of the Columbia hills using the full caperbilities of the IDD and Mini-Tes. It will not be told by joy-riding the the highest thing they can find.
