For some children the ride to school can be a drag, but for the Sims family from Hemel Hempstead it is quite the opposite.
Every day 15-year-old Jake, 12-year-old Lewis, Ella, eight, and Harrison who's three, do the school run with their mum Rachel in a replica American police car from the PlayStation game Need for Speed.
The Dodge Avenger has flashing yellow lights, and distinctive stickers. Unlike a real police car, it has no siren. Everywhere the family go, the car gets a lot of attention. People have asked to buy it, others want photographs and Rachel says one man was so busy staring he tripped over some bins.
The car was built to promote the video game, but 18 months ago Rachel's partner Simon saw it and bought it. The couple say that because it is black and white, with American markings, you can easily tell that it is not a real British police car. Officers did once pull Rachel over, but having looked at the car they let her drive on.
Far from being embarrassed, Rachel's children love the car and say their friends think it is fantastic. 12-year-old Lewis says he cannot wait to be hold enough to take it for a spin himself.
Rachel and Simon only bought it for a bit of fun, but now they say that it is getting so much attention they may start hiring it out for weddings.
