Dimples are passive, this thing is active.
1) As it stands, it's the dead air in the lowest strata of the turbulent boundary adjacent to the trucks body surface boundary which is protecting the attached flow.
2) The truck is already fully immersed in 3-D micro eddies transporting momentum from the outer flow all the way to the boundary, pinning the air.
3) I'm unsure as the the premise of how the plasma actuators would improve the existing situation.
