Yet at the same time it poses clear risks to the provision of equitable and sustainable mobility for all. These risks include replacing well-understood business models and the regulatory framework governing them with a greater reliance on services whose business models are in flux and whose long-term financial robustness is not yet proven. There is also a risk that a shift in service from traditional public transport to ride services could lead to a loss of travel options for those with mobility impediments since ride services currently do not face the same accessibility requirements as public transport. Other risks could include increased congestion and environmental degradation and an erosion of equitable access opportunities.
