The TurboChaser was heading directly either straight for the van or for one of the parents. It was a stand-off, a game of chicken. And, so far, none of the parents looked like they were going to chicken out. In a terrible moment, which she felt immediately bad about, it did cross Amy’s mind to think, Would anyone really miss Colin and Norma? And then she realised, yes, someone would – Janet.

Amy carried on heading directly towards them, hoping that at least one of the parents would break. Sanjay in particular didn’t look too happy – his eyes were flashing towards Prisha in a very “Are you sure about this?” kind of way. Amy could see her mum as well, who though she appeared brave and steadfast, was also, from the look in her eyes, pleading. Pleading for Amy to just stop the car and give up.

But she wasn’t ready to do that. Not yet. And, behind her, she could see the supercars getting very close now. Then she noticed something. Colin and Norma had stopped holding hands. Because Colin, it turned out, had another enormous packet of baked-bean-flavour crisps, and had chosen this moment to stuff a few into his mouth.

Both Amy’s hands were gripped tight on the steering wheel. In a flash, she lifted her right hand off, and reached over to press the button she needed.

From the parents’ point of view, the vehicle that was coming straight for them suddenly got much thinner and more like a rocket. All the wheels went into a single line, and the motorbike version of the TurboChaser swerved at the last minute away from the van and, with a whoosh!, snaked through the small gap between Colin and Norma created by Colin’s need to eat crisps.

“What happened there?” said Colin, looking up, munching.
