The UK driverless-car startup Wayve is headed west. The firm's cars learned to drive on the streets of London. But Wayve has announced that it will begin testing its tech in and around San Francisco as well, which brings a new challenge: Its AI will need to switch from driving on the left to driving on the right. As visitors to or from the UK will know, making that switch is harder than it sounds. Your view of the road, how the vehicle turns--it's all different.

The explanations show how an AI model works, the expected impact, and any potential human biases. Doing so builds trust in the model's accuracy and fairness. And the transparency encourages AI-powered decision-making.
