A survey of US mobile phone users by Jupiter Research suggests that, while only three percent use mobile navigation services such as maps and turn-by-turn instructions, parents and children are two distinct groups that would like to see greater tracking technology made available – for two different reasons.

Parents of under-13s, unsurprisingly, would like to be able to track the location of their children, with 42% saying they’d be interested and willing to pay for such a service. In the US, a relatively small number of under-13s own mobile phones.
