LAS VEGAS – Googling the nearest gas station, sending email from your smartphone, or booking a table at a restaurant: Those are all things you shouldn’t do while driving. But so many drivers have grown accustomed to their on-the-go tasks that automakers are increasingly trying to make those things easier to pull off with both hands on the wheel and both eyes on the road.

As General Motors and Ford commissioned ideas from app makers this week, the possibilities for what you can do with your vehicle’s steering wheel buttons, microphone, speakers and internal gauges are quickly expanding.

How would you like to choose your favorite tune by simply uttering the song’s title, turn your car into a mobile Wi-Fi hotspot, or respond to an ad you hear on the radio without lifting a finger?

At the International CES show, General Motors and Ford launched programs that will open their designs to developers, inviting them to create software applications for future car models. It’s a relatively new strategy for car makers, but one that many gadget manufacturers employ, including Apple, which did it for the original iPhone in 2007.

The programs free the automakers from having to keep pace with new technologies by tying the functionality of their cars’ internal systems to advances in smartphones.

Ford Motor Co.’s app developer program, called Sync AppLink, “is a way for (the company) not to worry about the next big app,” said product manager Julius Marchwicki.

General Motors Co. said its framework “gives developers a whole new sandbox, with wheels.”

In some ways, though, the current systems inside cars have a long way to go to provide the functionality that smartphones have offered for years.

For instance, in a demo of Ford’s new integration with music service Rhapsody, you can wirelessly sync your phone with the car and listen to playlists you have already created by pressing the voice button on the steering wheel and saying “play playlist 1.”

But you can’t just choose a track by voice on a whim, which is part of what makes these unlimited streaming plans attractive even at $10 a month.

Saying “Bruno Mars” to your Ford car won’t pull up “Locked Out of Heaven,” although typing it on Rhapsody’s website or smartphone app can. The same is true of Pandora’s radio app in Ford cars.

Rhapsody CEO Jon Irwin said that it’s really just the beginning for automakers to work more closely with high-tech content providers.

“This is the first step in what’s going to be a really exciting year,” Irwin said. “As that technology evolves, you’ll see it get better and better.”

Toyota’s use of voice is the most advanced of the auto providers, even though it had nothing new to show at this year’s CES.

When it upgraded its Entune service for Toyota cars and Enform for its Lexus line at CES last year, drivers got the ability to use their voice to control several key apps, allowing them to say, for example, “Adele” to the iHeart Radio or Pandora app to create a custom station with tracks from the British singer and others who sound similar.

Voice commands also worked to buy movie tickets, make restaurant reservations through the OpenTable app and get turn-by-turn navigation toward cheap gas.

Both Toyota’s systems require yearly subscription fees after free trial periods.

Given that Google, Toyota and others have been testing driverless cars, it’s not hard to imagine the day when your smartphone will hear your stomach gurgle, get Burger King to send you a coupon, and then guide the car up to the drive-thru window for a quick bite.
