So did you try Kama Sutra when you were little? lol I see the point of the ad is 'Try smart, it's different'. Kinda like the Apple 'Think Different' ad. I think it would be a ok ad in the US. Sitting in and driving a smart is half the 'sales battle'.
A TV ad with the SUV and smart with real people at a gas station would be good.
And one showing SUVs and Trucks in a traffic jam with only one person in each SUV, then to a road with smarts moving along. Another with the same SUV crowd looking at their gas gauge and pulling off to get gas while the smarts just drive on.
