The self-driving car's mission is a circular (no beginning, no end) one like the CRLMM described in the previous chapter:
- If it is in a parking lot, it can be activated by a home or a shelter
- If it is at a given home, it will go to a shelter
- If at a shelter, it can go to a home or a parking space
- If it needs recharging, this can be done at a recharging space (or more probably at a parking space), which is already the case in some cities
At one point, the self-driving car has to go from a home to a parking space. This part of its itinerary is the subject of the following sections.
