值得追问的是，智驾系统的语音控制系统的权限边界在哪里？这起事件发生之后，也有其他品牌的车主对自己的汽车进行测试，不少品牌的车机系统同样做到了“关闭大灯”。夜间行车的车灯开关，是否可以如此轻率地以语音完成，当然是非常值得商榷的问题。试问，在电脑上删除文件、卸载软件况且还会跳出对话框要求用户二次确认，事关行车安全的车灯，恐怕不应该仅凭一句话就可以贸然关闭。车机的语音识别系统理应留出足够的安全冗余度，引入二次确认、声纹鉴定等方法，避免意外。
RE# started as a research project to combine multiple things - first we wanted to bring boolean operators back from the 1964 paper where they originated, then we wanted to extend the .NET NonBacktracking engine, which was, the way i see it, being held back by backwards compatibility (i.e., a safe drop-in replacement for the PCRE existing engine, which meant that it had to support the same features and semantics). we wanted to break free from those limitations and see how far we can push the new engine without worrying about compatibility.

当如此巨大的计算系统同时运行时，每一块GPU都需要与其他GPU不断交换数据进行同步计算。如果网络传输速度跟不上，GPU就会停下来等待数据，这意味着大量算力被浪费。
