I am aware of the sequence but again it is irrelevant. He had the authority to order her out from the moment he pulled her over until the stop was over.
There is debate among experts as to whether he could order her to put out the cigarette. It is a grey area. But her demeanor was certainly justification for him to feel it would be safer to have her step out, so he could look for bulges that might be weapons or safely look for weapons or drugs and paraphernalia in plain sight.
There is legal assumption that the officer’s safety is at risk throughout any stop, so even the slightest bit of concerning behavior by the driver would be viewed as a valid reason to order her out, though he needs no specific reason at all.
ROTFL! There's GOT to be a pony in that load, somewhere!
