Market research firm Harris Interactive's AutoTechcast on Wednesday reported that almost two-thirds (65 percent) of adult automobile owners who also have iPods or other MP3 players use the device in their vehicles.
The automobile owners use some type of adapter to use their player while driving, the study reports. Overall, about one in ten (12 percent) of all adult automobile owners also have iPods or MP3 players; usage in vehicles is heavily weighted depending on the driver's age. Younger drivers, 44 and younger, are most likely to use the devices.
The study was conducted among 12,857 U.S. adults ages 18 and over who own or lease a vehicle, according to Harris Interactive.
I definitely agree with that. I primarily use my iPod while driving or while running/working out. And when my car stereo was stolen last summer, I chose my new stereo based on what was cheap and had an aux in jack in the front so I could use my iPod with it.
