来源：环球时报 更严格的规则可能会淘汰一些小型企业，但是对消费者来说，意味着驾驶更安全、更可靠。（刘长煌 译） 针对相关问题，有关机构正在介入对智能驾驶的监管，并根据相关企业意见制定新规则。规则出台后， 可能会重新定义全球汽车产业。 政策调整背后蕴含着战略考量。中国将智能驾驶视为与西方（特别是美国）竞争的新前沿。在美国，监 管滞后使得特斯拉等公司不得不应对各州法律带来的复杂局面。北京方面希望通过实施明确、严格的标 准，避免硅谷"快速行动，打破常规"理念所带来的陷阱，同时保持技术优势。埃森哲公共有限公司的马 库斯·穆西格说："中国的做法反映了'摸着石头过河'理念。他们正谨慎而果断地前进。" 业内专家说，任何技术范式转型都难免发生事故，关键是避免信任崩塌。问题不在于事故是否发生，而 在于是否会造成不可逆的公众信任危机。 作为全球最大的汽车出口国，中国仅今年6月就出口20.5万辆新能源汽车，其监管选择实际上树立了全 球标准。更严格的规则可能暂时减缓海外市场的采用速度，但整体利大于弊。业内专家表示，清晰的指 导方针会让外国监管机构放心，最终将加速而非阻碍中国的出口势头。 与此同时，美国则面临进一步落后的风险。由于缺乏 ...
