I know it isn't the main point, but I think its somewhat presumptuous to suggest he would be praying whilst actualy driving. Also, the fact that he was wanting to pray for safety suggests that safety is a priority for him.
Magic, if you read the linked article, he did indeed pray while driving, and led the kids in singing religious songs. If safety was the priority, then why did his religion get mixed in at all?
Whoops. I missed that. I stand corrected.
