What is a key regulatory difference between a traditional taxi-cab and a rideshare (TNC) vehicle in Alberta?

1. Taxis can accept street hails and use taxi stands, while rideshare drivers must only accept trips booked through an app
2. Taxis do not require safety inspections, while rideshare vehicles do
3. Rideshare drivers do not need a driver's licence, while taxi drivers do
4. Taxis are exempt from speed limits, while rideshare drivers must obey them
