"What if every city banned cars by 2030?"

The economic lens sees a €2 trillion automotive industry collapsing. The social lens sees children playing in streets for the first time in a century. The political lens sees the most powerful lobby in history mobilising against it. The environmental lens runs the carbon numbers. The ethical lens asks who has the right to mobility when cars are gone. The cultural lens watches the death of the road trip as national myth.

That's not seven separate searches. That's one prompt in Yesbrainer. One idea, analysed through seven lenses simultaneously, with tensions mapped, blind spots identified, and the surprising consequence surfaced.

What's your scenario?
