与两年前不同，这辆无人驾驶出租车的驾驶座上，不再有监督员。驾驶过程中，方向盘自顾自地旋转，礼让行人，保持车距，转弯减速让行，文明得令人汗颜。稍有不太便捷之处，则是在落客时，车辆只能生硬地停靠在地图上约定的地点，乘客难以跟其“商量”能否停靠在更方便的落客区。
Industrial production of kanten (the Japanese name for agar, which translates as “cold weather” or “frozen sky”) began in Japan in the mid-19th century by natural freeze drying, a technique that simultaneously dehydrates and purifies the agar. Seaweed is first washed and boiled to extract the agar, after which the solution is filtered and placed in boxes or trays at room temperature to congeal. The jelly is then cut into slabs called namaten, which can be further processed into noodle-like strips by pushing the slabs through a press. These noodles are finally spread out in layers onto reed mats and exposed to the sun and freezing temperatures for several weeks to yield purified agar. Although this traditional way of producing kanten is disappearing, even today’s industrial-scale manufacturing of agar relies on repeated cycles of boiling, freezing, and thawing.
