I played it in a pub a handful of times when is was in my teens before we ended up moving and never seeing it again. It's a top down driving game from the early / mid 90s and I can't remember its name. It started with a cut scene of some kind and ended with your mini character either running (or being chased?) to a car and driving through some barriers or barrels - then as you take control of the car - the view pans out and it becomes a top down driving game. I'm sure 12 DOHC was in the title somewhere.
