车顶有一个“大凸起”，常出没于北京，这车到底有什么用？
眼前这辆颇为怪异的车想必大家都看到了吧？与寻常汽车比较，其实这辆车也没什么特别的，只是汽车车顶上的大凸起比较吸引人。有人会说这车应该是车主的个性改装吧，其实并非如此。说句题外话，汽车改装要是改成这样真够失败的，它不是改装车，它只是无人驾驶汽车！
车顶有一个“大凸起”，常出没于北京，这车到底有什么用？我们眼前就是无人驾驶汽车，现在无人驾驶汽车已经可以在北京进行测试了，而且汽车数量还达到了54辆之多。目前，无人驾驶汽车还在开发之中，离技术成熟还有很长一段路要走。据了解，北京的无人驾驶汽车去年就开始测试了，去年无人驾驶车一共驾驶了15.36万公里。虽然里程数不算多，但也为研究人员提供了宝贵数据。
北京的这54辆无人驾驶汽车，其实来自众多品牌，有北汽新能源的，同时也有蔚来汽车的，全国一共有8家企业参与了无人驾驶汽车测试项目。在全国范围内，北京是第一个展开无人驾驶汽车测试的城市。为了给无人驾驶汽车铺路，北京早在2017年12月份就公布了无人驾驶汽车相关的法规、测试路段以及事故保险细则等等。
北京成为无人驾驶汽车首测地其实不用大惊小怪，毕竟北京是全国的科技中心，在科技创新上北京必须一马当先。无人驾驶汽车上悬挂道路测试临时牌照，为了保证安全，这些无人驾驶汽车只能在规定区域测试。发放道路测试临时牌照解决了无人驾驶汽车上路的问题，为了能够保障安全以及避免一些纠纷，北京还特意出台了专门用于无人驾驶汽车的事故保险。
现在来看，正在北京进行的无人驾驶汽车测试好像是有模有样，但真实情况却是这样的。其实这些无人驾驶汽车并非真正无人，车上还是有人的，只是人不用开车，而当出现紧急情况的时候，车上的人才会进行干预。
