How do you think she will go?

Drive off into the sunset. AFAIK she's not being killed off.

A tearful goodbye to Roy and Michelle. Black cab for one. End of Carla.

Spaceship

Nick to get arrested for doing something serious while in one of his moods. Carla walks out on him, and out of Weatherfield, during his trial. This then lays the foundations for a Carla/Connors vs Platt feud if/when she returns.

What I hope: She runs over Tracey, killing her, before going on the run.
What will probably happen: She realises she doesn't have much of a reason to stay on the street so gets in a black cab and leaves

Nothing spectacular, the way the soap is at the moment she will just say her goodbyes and drive off into the sunset. Zzzz

Borethenation street

Trading insults with Tracy out of a black cab window to ensure this pathetic feud carries on as long as possible.

Run over by Izzys wheelchair

She sees Tracy in the road, she then drives towards her, Tracy then jumps out the way while the car goes into Dev Alahans shop. Tracy is then screaming like Sunita when Dev says

Maya your still alive

Chased by an axe wielding Kate Oates.

Personally I think she will miss Tracy and go straight into the house and die in the fatal accident.

I think she's going to die somehow. She's been utterly exhausted as a character, what else is there for her? What reason would they have to bring her back? They can't take her any further as she's done everything, the only thing left for her to do is either bow out in a blaze of glory or a tragic ending, leaving Nick kicking himself for loosing both her and the bistro for nothing.
