For various reasons, backing into parking spaces is not the best option. It can be difficult to judge the size of a space and how much space you need to reverse safely.
There is also the possibility that you will miss something in your rear cross-traffic alerts and collide with another vehicle. Even with the most advanced safety technology, it is easy to make errors when reversing into a small space.
Aside from the risks, it can be extremely inconvenient for other drivers who must wait for you as you slowly maneuver your way into the spot, especially in a busy lot with few available spots. It’s so dangerous and inconvenient that it’s illegal in some places.
