Most motoring enthusiasts would have memories of racing toy cars around the bedroom floor but, no matter how many 'vroom vroom' noises you made, they never came to life.
Speaking of inanimate objects that don't usually come to life, Lego has recently made the jump from living rooms to the silver screen. You can probably see where this is heading.
Renault Sport has created a short video combining the classic bedroom-floor GP with a Lego Renault F1 car, a fire truck and an old-fashioned wooden toy. Think of it as Toy Story crossed with the Lego Movie and Speed Racer and you'd be close.
We probably don't need to tell you the Renault Sport racer wins, but, well, the Renault Sport racer wins. That's a bit of a contrast with the Renault F1 team, which returned its best result of the season two weeks ago, with Carlos Sainz Jr. finishing fifth in Azerbaijan.
