未来器官移植靠什么 3D打印部件愈加成熟

The potential benefits are hard to ignore. Each year 30,000 people die in traffic collisions in the U.S. Considering that 90% of U.S. auto collisions are blamed on human error—some 40% are the result of factors such as alcohol or fatigue—we have a lot to gain by outsourcing the task of driving to computers.

这样做的潜在好处很难让人熟视无睹。在美国，每年有3万人死于交通事故。考虑到其中90%的车祸是由人为失误造成，而且大约40%的事故缘于酒后驾车或疲劳驾驶，把操控汽车的任务交给计算机会让我们受益匪浅。

If 10% of vehicles were self-driving, it could reduce the number of accidents by 211,000 and in turn save 1,100 lives,according to a 2013 study by the Eno Center for Transportation in Washington, D.C. If 90% of vehicles were autonomous, an estimated 4.2 million accidents would be prevented and 21,700 lives would be saved.

华盛顿非营利智囊机构伊诺交通中心(Eno Center for Transportation)在2013年进行的研究表明，如果美国10%的车辆可以自动驾驶，交通事故就会减少21.1万起，1100条生命就能得到挽救。如果自动驾驶汽车的比例达到90%，就可以避免420万起车祸，2.17万人将因此获救。

Technological advances often come with unintended consequences, though, which is why these predictions support Pettis’ case that organ donations would be adversely impacted by safer driving. Motor vehicle accidents are the largest contributor to organ donations after natural-cause deaths. Since 1994, 16% of all organ donations came from motor vehicle accidents, according to the U.S. Department of Health & Human Services.
