I think you may mean Level 4. The difference between 4 and 5 is that 5 doesn't have any territory/environmental constraints, but you said you don't mind those.
If they require high speed cellular service then the system can’t scale to level 5 driving. Add a Starlink dish on top and the hardware could eventually scale to the entire continental US etc.
