To me it's no big deal to turn the car off and tap the on/off button once again with foot off the brake to turn the radio back on. And as for the phone, if I'm not finished with my call when I want to turn the vehicle off, on my iPhone I just go the audio source on the phone, which is the main screen showing when your talking on your phone, and switch it from the car to the phone. It's one tiny little extra step. If you plan to talk on your phone or listen to your radio in the car after turning the engine off, you're subject to the car turning the power source off after a few minutes anyway to preserve the battery life. I've driven Infinities for 8 years, and I truly think you get a lot for your dollar investment compared to other vehicles in this class.
