Why French people park their cars like that?

When I was in Paris, I was wondering why the French peoples like to park their cars bumper-to-bumper.






I can think of a few possibilities:

1. To show that French peoples are indeed romantic. They proved it from the way they parked their cars.
2. This is because France has a small parking space which could only fit the size of a Smart car.
   
3. To avoid their cars from being stolen.
   

What would happen if we Malaysians park our cars like that?
