本周三，一辆无人送货车出现在浙江杭州街头。
The smart vehicle was developed by Cainiao, a company devoted to building a smart logistics network in China.
The new vehicle, which has a top speed of 15 kilometers an hour, performed well in a 10-kilometer-long road test. It is expected to be fully operational by the end of this year.
