Good analysis. We had a few more when we did the stakeholder analysis:

For passengers:

• - Massive loss of privacy as ride data collected and harvested for patterns.
• - Tipping becomes mandatory to maintain your reputation within the service
• - Loss of choice for passengers with accessbility needs (as a market segment they’re too small to matter, so they depend on regulated taxi industry)

For the city:

• - Loss of tax base
• - Loss of ability to regulate for passenger safety, accessibility, etc. (multi-national corporations wield far more political power than traditional taxi companies).
• - Loss of all supply-side management options.

For society:

• - Accelerates trend towards gig economy and lower wages for everyone
• + potential to increase trust in society by leveraging online reputation systems
• - drives out free ride-sharing schemes, as people come to expect payment for rides.
