HD will be in 140+ models of new cars by the end of 2013.
It's not "flopped." It's just beginning.
Suggesting the Commission is taking bribes is ridiculous.
Do consumers even know it is there? Do auto dealers? Last time I checked, they did not. They either think it is satellite radio or give you a blank stare. Same thing as AM stereo. Most people didn't even know it was in the car. Given a choice, they will select satellite, pandora, bluetooth, auxilary, DVD, MP3, USB, iPod interfaces over HD. It may be in 140 models of car as a option - that doesn't mean its actually available in dealerships, nor does it mean the dealer has ordered vehicles with it installed for their inventory. They go with more popular options.
My dad bought a new car in 2010 a Toyota Avalon, comes with XM and and 3.5 jack for an IPOD, plus a USB port for Thumb Drives. He used to use thumb drives loaded with a couple of CDs, now mainly uses the XM.
