It was inevitable this would eventually happen. Ford is “test driving” (pun intended) letting users upgrade the firmware of their entertainment systems via USB drives. Given these are just software driven devices not that different from a mobile phone, it’s obvious this would eventually happen. Overall it’s a good thing since bugs in increasingly complicated systems can be fixed after the car is bought without getting it serviced.
However it does create some complexities. As systems become more integrated and more computerized, you must wonder. Will it eventually be possible to brick your car? Or even worse. Will it be reduced to a cell phone with a 2 year upgrade cycle?
