It appears from the 2nd picture that there's not even a passenger in the van
Your right.
I don't think anyone was ridding shotgun.
When I passed him it turned out to young guy dressed like a painter and looked about 5' tall and 100 lbs......OK a bit bigger but small none the less.
I would hope he used real cation on the off and on ramps.
For locals this was 495 South, the on ramp you see is from 24 South.
