If uniformed police officers are pulling you off the road in marked cars with flashing lights, your participation is hardly voluntary.
I was going to say that I think this fine because it is voluntary, however you make a fair point, this is far from voluntary
as voluntary participation is normally indicated by the individual placing themselves in the situation, not with the "assistance" of being directed to pulled over.
I'm not convinced that they are ill motivated, however there must be a much better way to garner subjects for this research.
