What is the practical difference between street-hail and ride-hail in LTA's P2P framework?

1. Street-hail is flagging a taxi on the street or at a stand; ride-hail is booking through a phone or application
2. Street-hail is only for buses; ride-hail is only for lorries
3. Both mean the passenger must negotiate cash fare privately
4. Street-hail is illegal for all taxis
