You can use this to answer questions like below:

1. How much of the roads in the world passes through dessert?

2. What is the chance that you would see a person if you had been driving all over?

3. How much of the streets are in urban areas?

And so on...

All you need to do is just press next few times and count!

That assumes that Google hasn't prioritized areas with higher population for Street View photography.
