Many modern cars come with parking sensors that help you avoid hitting the car parked behind you. That’s great, but they do very little to help you avoid getting too close to the curb and scratching your precious mags. SmartRim changes all that. It’s an ultrasound-powered proximity sensor that attaches to the inside of each wheel well, and connects to a smartphone app. As you park, the sensors will indicate how close to the curb you are and help you avoid hitting it. There are no wires, so installation is a breeze.
Additional features include accelerometers that can tell you if the valet took your ride for an unhealthy spin, and the ability to use regular AA batteries for power; a single AA battery will last up to 1,000 parking cycles.
It’s currently being funded on Indiegogo, and a set of 4 SmartRim sensors will cost you $345. That’s a lot, but if you really think about it, you only need two for the back wheels, which is a very reasonable $179 pledge at the moment.
