This is what the Dubai Festival City parking garage looks like. Not as large as Avenues perhaps, but look more closely at the picture above. Notice those little lights above the cars, they are all red. And the one above the empty spot, its green. 

Now wouldn’t it be nice to have this in all parking lots? Saves a ton of time finding a free spot and will also reduce the level of carbon monoxide in the garage from not having to get in and out of lanes.

I did do some experiments while I was there.

1) If you stand under the “thing”, it turns red.

2) If you jump while you’re under it, your head will break the “thing” (be sure to wear a helmet).

3) If you park a car with the sun-roof left open, it will keep blinking between green and red :)
