They are somewhat useful, but I believe they are more of a distraction. Anything that makes us look away from the road, even just for a moment, is risky for both drivers and pedestrians. These devices often have technical issues, and drivers might need to re-enter their destination, even while driving. So, I don’t think they really help drivers.
它们在某种程度上有用,但我认为它们更多是一种干扰。任何让我们从道路上移开视线的事物,哪怕只是一瞬间,对司机和行人来说都是危险的。这些设备经常出现技术问题,司机可能需要在开车时重新输入目的地。所以,我认为它们并没有真正帮助司机。
