On Monday, General Motors gave additional details on the ability of their future cars to access AT&T’s cellular network through OnStar’s information and emergency aid services.

Although GM believes that this technology will be the next great platform, there are still a number of hurdles that will hurt both GM and AT&T from making this a popular option.

First, many customers will already own a smartphone with mobile hotspot capability and it is unlikely to be popular for them to have to pay additional money for another pricey AT&T data connection that gives them little data. Therefore, if you plan to consume any reasonable amount of data on that 4G connection in the car, you will have to pay yet another highly-priced internet bill per month.
