Maybe I'm misunderstanding you, ELOC, but Kevin DID go into DR's driveway and turn around according to Joy's blog.
"Kevin drove all the way into Rassiers driveway because he didnt realize it was a driveway. From 16th Avenue, the driveway actually looks like a dirt road....As for where Kevin turned around in relation to the light pole
All three turned in a counter-clockwise direction, yet the two cars Dan saw took a sharper turn, away from the garage/light. Kevin took a slower, more leisurely route in the big part of the driveway, closer to the light. And while none of them came directly into the light under Dans bedroom window, he said he still had a good view of the two cars he did see. In both cases, after the cars turned around, he hurried to a window on the opposite side of the house (the south side) and watched them zoom up the driveway. This was definitely out of the ordinary and he wanted to know who it was. Hed never seen any car drive like this in their driveway before."
