The SmartRim is a device aimed making this a thing of the past.

The SmartRim was created by technology entrepreneur Steven D. Domenikos with a view to giving drivers a clear idea of their proximity to curbs and other unsighted car wheel obstacles. It employs a sensor that measures the time taken for ultrasonic waves to reflect off nearby objects dozens of times every second.

The device also contains a micro-electromechanical sensor that is used to constantly measure acceleration and can reportedly detect actions like a person entering the car. This helps it to be aware of its environment and allows it to become active only when necessary, thus saving energy.

Installation of the SmartRim is claimed to take just a matter of minutes.
