What are the two protrusions behind the parking space?

[StTessa]

The two protrusions behind the parking space are wheel stoppers. Here is some additional information: 1. Function: They effectively prevent the possibility of collisions with other vehicles and reduce the risk of scratches, providing better protection for your car. They are easy to install, can be combined freely, and are suitable for parking lots, underground garages, etc. Wheel stoppers are installed at the rear of parking spaces to limit vehicles to the optimal parking position. They are eye-catching, aesthetically pleasing, and easy to install. Currently, they are the best facility for accurately limiting vehicle parking positions. 2. Precautions: Sometimes, parking spaces in underground garages are scarce. When finding an empty space, drivers often drive straight into the space headfirst, occupying it first. However, when retrieving the car, they may find it very difficult to back out. When steering to back out, the front of the car can easily scrape against adjacent vehicles. Therefore, try to avoid choosing parking spaces that are difficult to park in, such as those near pillars, lift platforms, ramps, or those surrounded by densely parked vehicles.
