"They" are the 1320video crew....... Specifically, the "front man", who was at the top end talking to Tom, and it appeared he was driving the golf cart while towing Tom back to the pits.

I saw this on the day 2 recap coverage.

The reason I question it is because, I think it was day 4, there was a car dead at the top end, and the guys in the tower were saying if he got a tow back to the pits by someone other than another competitor he would be "out".
