Once the prototypes have proved effective and practical, they should scale quickly without public incentives. As with other innovations – such as mobile phones, e-books, digital photography and music, and flat-screen televisions – large-scale deployment will occur when the new technologies reach the market tipping point, when their value to consumers exceeds the costs to businesses of supplying them.
一旦原型系统被证明有效实用，它们应该就能在没有公共激励的情况下迅速扩大规模。在其他创新的影响下——比如智能手机、电子书、数字照相和音乐、平板电视——大规模部署将在技术到达市场引爆点时发生，即它们对消费者的价值超过了供应它们的企业的成本。决策者将只需负责保证扩张的系统的安全性。
