Please explain the problem. Why is a tank needed? Why not just mop the water up with towels?
2- In the new models of car flooring, spaces have been designed to keep more water volume, so it is not easy to draw water completely with a towel
The tank can also be used to drain car floor sand. Imagine that after walking on the beach sand, some sand is transferred to the car. To drain the sand, it is enough to wash the car floor with a small amount of water and direct the sand into the tank.
Carpets inside cars can play a big role. The idea is good if you accidentally knocked over a bottle of water, but this situation is rare. If it is just a small amount of water, sand, or other things during normal lifetime, the carpet can absorb the water, and then people only need to take out the blanket and pat it to remove the sand. It is not necessary to waste more water on the tank (because if there is sand, you still need to consider clean it)
Thanks for your comment, some people may use carpets in cars or trucks, but some people use car mats to protect carpets from stains and stains. When there is sand on the car's mattress, you can take the sand out and separate it, but some car's rear mattress is one piece and it's not easy to do. The idea adds another property to car mattresses, and that is to get water or sand out of your car without pulling out the car floor.
