L3因为是人车共驾，责任划分、保险赔付等方方面面都需要考虑到。而L4不存在这个问题，出了事就是厂家负责。因为责任明晰，所以落地争议也较少，这就是现状。但是只要法律层面解决L3的责任划分问题，大规模普及也并不是遥遥无期。

During its Unpacked event today, Samsung announced three new Galaxy S-series phones as well as the latest generation of its earbuds, the Galaxy Buds 4 and Galaxy Buds 4 Pro. Pre-orders are now open and the new devices are set to ship March 11. As expected, this year’s models aren’t drastically different from last year’s, but all the phones are equipped to better handle the Galaxy AI experiences such as Now Nudge that offers suggestions based on your activities and a more conversational assitant in Bixby (or Gemini or Perplexity depending on your preferance).
