Smart parking technologies - for idiots like me

As the saying goes "when there is a demand, there is a supply"...so for parking idiots like myself, the invention of rear parking sensors in vehicles is indeed a blessing. When the rear or the bumper of the car is almost near the wall (for reverse parking), the sensor starts to beep and you know you have to stop reversing. With rear sensors to detect close proximity of objects, there is even the rear view mirror with integrated wireless LED distance display. That is good if there is a low curb and no high barrier wall for the sensors to be in effect for proximity, and for beeping you. You can actually judge the distance from the rear view mirror.

And it must be nightmarish to find a parking lot or space in high-density cities such as Singapore. Within the public parking garages, there are individual parking lots that hide a sensor at the ceiling-overhead of each lot. This sensing detects whether a vehicle is parked at the lot and sends a signal back to central sensing system which then signals entering vehicles into the parking garage to empty parking spaces. Cool, isn't it?
