People exist outside of your vehicle. Danger can be something that you impose onto others by operating heavy machinery. It can also refer to danger of property damage or non-life threatening injury. You and your car might be fine in a parking lot incident, but the kid that you ran over will not be.
For reference, in the US, for just reported vehicle accidents per the National Safety Council:
- 20% of all accidents occur in parking lots
- 500 people per year are killed in parking lots
- 60k injuries per year in parking lots
Given the low speeds inherent to parking lots, and the extremely low share of miles and time spent there, it is a remarkably dangerous place. It doesn't take a genius to figure it out; parking areas are by definition where humans and heavy machinery operate in the exact same spaces.
