Mrs McCann was scared, being in an accelerating car. I can understand that. I like to drive fast (when needed), but I hate to be driven fast. However, in dramatic circumstances, one would think that the idea of Madeleine being found would have overwhelmed her and her fears.
Below are Kate's and Amarals descriptions of that event. .
Which version is most likely to be true - considering this was the very next day after Madeleine had disappeared and hopes would still be relatively high that she would be found - and also considering that Amaral wasn't there to see how they reacted.
From Kates book
It was seven thirty by the time one of the PJ officers drove us away from the polilce station. Angela Morado came with us. Ten or fifteen minutes into our journey the police officer had a call from his station. He said something to Angela, who explained that he'd been ordered to return us to the police station straight away. He wasn't allowed to tell us why. Already driving at quite a scary speed, he suddenly swung the car into a U turn, floored the accelerator and drove us at a life-threatening 120mph plus back towards Portimao. I cannot overstate how terrifying this was. Had Madeleline been found? Please God. Was she alive? Was she dead? Gerry and I clung on to each other for dear life. I was crying hysterically and praying for all I was worth.
Back at the police station we endured at least another ten minutes of torture in the waiting area before somebody showed us a photograh,clearly taken from CCTV, of a blond child with a woman in a petrol-station shop. We weren't told anything about this, just asked whether the little girl was Madeleine. . She wasn't. And that was that. Again we were sent on our way,
utterly devastated. From Amarals book
FIRST EYE WITNESS STATEMENTS; KATE HEALY'S SURPRISING REACTION
Madeleine's parents are already back in Vila da Luz when we receive photos taken on an area of the motorway: you can make out the figure of a little girl, who looks like Madeleine, accompanied by a couple. These images come from a CCTV camera on the motorway linking Lagos to the Spanish border. The McCanns are asked to come to Portimao in order to proceed to an identification. It's the end of the day. Kate Healy seems annoyed at coming back and made uncomfortable by the speed of the police car taking her. We are somewhat astonished by her reaction, as if she was not expecting to get her daughter back. The identification turns out negative.

IMO opinion in those circumstances - to call them back like that with no explanation, even if it was unintentional, bordered on the sadistic. It would appear that even the driver thought something extremely important had happened - hence the speed at which he drove them back to the police station imo.
