Why are you doing anything with your phone, including ascertaining it's on a low charge, while driving? Plug your phone in at the start of your trip if it needs charging.
The real killer app for me, though, is wireless charging in the car. I’ve got a Qi charger built into my car (and Qi phone mounts are readily available as retrofits for cars that don’t) and it’s really handy (and likely safer) to be able to just throw my phone in the pad if I realize it’s low while driving rather than having to fumble around with a cable.
