如果自己的汽车出了毛病，用移动电话请求帮助，要是在路边见到有人像是车出了故障，不要接近他们，同样用电话寻求帮助。

If you break down, use your mobile to call for help, and also to call for help if you see someone who looks as if they have broken down at the roadside, rather than approaching them.

此类“近距离通讯”让电话可当作火车票与办公室通行证来用，那么用电话当家门钥匙或车钥匙也是顺理成章的事。

The same “near field communication” chips enable phones to be used as train tickets and office passes, so acting as front-door keys or car keys as well would not be a giant leap.
