I have a similar question.

When djellison explained current wheel directions, he wrote:
"The wheels will be pointing in funny directions because at the end of a drive they turn the rover in place to put it in the best position for the UHF passes that afternoon and the following morning."

Does rover make turn in place at the end of drive automatically, even when it encounters an obstacle? Oppy went a half of planned day distance and sensed unexpected resistance. What instruction does she have for this issue? Is it "make turn in place for good communication"?

On the contrary, if they turn a rover by a command: did they send this command because they haven't got information about the problem yet, or did they decide to take close look at the problem after the turn?

Something like this?

It seems strange to me that rear wheels are turned in opposite directions. It isn't proper position not for straight moving nor for rover's turn. Moreover, the tracks seem to be corrupted between ridges, where sand wasn't deep. Could it be a software glitch which caused inconsistent turn of wheels and subsequent dig into the soil?
