Hi Tom. Do it from the top view (straight down / orthographic) not a perspective view. Eg like the image you had from the net.
...Think child's 'car mat' play area with a camera looking down on it. For example...http://www.thinkstockphotos.co.uk/image/illustration-play-mat-car-carpet-for-kids/523164891Then animate the camera slowly moving upwards (no side to side etc). Then animate the go-cart driving around the roads.
