I wouldn't recommend to do this while you are driving, but being able to shop via apps in your own car is pretty awesome.
Call GM’s new Marketplace app a good start, then pull up a seat to see what comes next. The system has the potential to save time and make everything from the daily commute to family vacations easier — but it still has plenty of growing to do.
Marketplace lets you order food, make restaurant and hotel reservations and find gas stations from behind the wheel. Two million drivers already have cars equipped with Marketplace. GM expects to that double this year.
I recently tested the feature in a 2018 Buick Regal TourX sport wagon. Among other things, Marketplace gave me a new appreciation for Dunkin’ Donuts and convinced me the system could become one customers rely on as GM adds features.
“Marketplace is in its infancy,” said Jake Fisher, director of automotive testing for Consumer Reports magazine.
