help vehicle gets rainwater

My friends started to take rain water in the car, was there such a thing as a biolay vehicle 206 single door
With the driver section, the driver is in the back part of the rain, the water is extremely heavy, it is not clear at first glance, but the mat is too wet.
my guess is getting through the door
Is it possible to go to the back section if it gets out of it? Could you give some information if you have friends who are looking up and not at all?
and when we park the vehicle, sometimes we park one side up to the lift, can it be picked up from the doors with the possibility of yawning?

Don't let the filters out at the door!

They were suppositories. There are sprays that make them flexible.

It is from suppositories.
