## Description of the bug
Title. This means that the van can very easily be made inaccessible by driving it up against a wall on the left side, blocking the only door.

## What's the difference with what should have happened?
The van should probably have multiple entrances and exits to discourage players from trying to abuse this.

## How do we reproduce this bug?
1) Spawn in the sekhmet hovercraft van
2) There's only one door
