It's all about perspective. I once wheeled with a guy, in a TJ Sport, that was new to serious off-roading. He kept coming on the radio and saying he felt like he was going too fast over the rocks. I figured it was just him being new. An hour or so into the trip, the distinct smell of burnt clutch was in the air. I asked him to stop, so I could take a look. When he got out of the Jeep, I noticed the transfer case lever was in 4WH. I asked him if he had been driving like that the whole time, and he said yes. I reached in switched it to 4WL, then told him to try that. The rest of the day there was no more burnt clutch smell, he was smiling, and never complained again about going too fast.
For the record, I did tell him in the pre-brief to use 4WL. Unfortunately, he forgot that part!
