The U.S Department of Transportation has refused to accept the ban on cellphone use in vehicles.

U.S. Transportation Secretary Ray LaHood said he won’t back a proposal to prohibit drivers from talking on cellphones, even hands-free devices, giving a boost to car makers and mobile-phone companies that stand to lose if regulators impose a ban.

Given that most smartphones have the ability to run software designed to support driving tasks, like turn-by-turn navigation, this makes a lot of sense.
