The speed bump in front of the underground parking lot was demolished by the road construction in the community. Who is responsible for the damage to the bottom of the car?

Responsibility of residential property.

Without the consent of the owner, the residential property should bear the main responsibility for removing the speed bump in front of the underground parking lot without authorization, because the facilities inside the residential area need to be maintained and managed during the residential management period to ensure the safety of the owner's life and property, and removing the speed bump without authorization has damaged the owner's vehicle, which has violated the responsibility of property management.

The speed bump in front of the parking lot is a traffic facility to slow down the speed of vehicles entering and leaving the parking lot and reduce safety accidents caused by speeding.
