What's a light-year, why is the earliest dawn not on the solstice, is the Sun hotter in South Africa, what causes neuropathy, can batteries short out in my pocket, is there a non-surgical solution to a squeaky voice, can my cell phone unlock my car and why does tapping a cup of cocoa make the pitch go up?

It would seem like an excellent addition to keyless ignition and keyless entry systems to tie it into a person's cell phone, perhaps activating it by proximity, like is done with the Prius.
Damn keyless entry and ignition! I have to take this blob thing out of my pocket to press the button, then I get into the car and there's nowhere to put it, so it rattles around on the dashboard or in a door pocket until I get out, and I can't find it. Now the great thing about a key is it's on a ring with my house key and anything else I might find useful, and there's a neat place to put it in the car so I know exactly where it is. And it's one less battery to go flat. The screaming frustration of having a dud battery or a message "key code not detected" just adds to the sheer pointlessness of this ridiculous invention. alancalverd, Sat, 28th Sep 2013
The Prius just detects the key's presence nearby. No buttons to press... Just leave it in the bottom of one's pocket or purse, or whatever.
