As a resident of LA ive noticed when I park somewhere im always stressed about making sure i find the parking signs denoting street cleaning and any no parking times. I think its be awesome if users could take pictures of parking signs that pop up when someone is parking to be like HEY LOOK AT THIS SIGN BEFORE YOU GET OUT OF YOUR CAR AND FORGET TO LOOK AND GET A TICKET OR TOWED. Am i mark Zuckerberg now?
