Care should be taken, when identifying niche scenarios where sufficient incentives exist for dynamic ride sharing, to consider whether solutions other than ride sharing would be more appropriate because those solutions provide greater value. For instance, in some scenarios where parking is at a premium, such as campus companies , efforts would likely be made to encourage shuttle bus and cycle usage, rather than ride sharing, because the reduction in parking is greater.

Furthermore, if you assume the opportunities for ride sharing (of any type) are limited to those scenarios where sufficient incentives exist, then opportunities for dynamic ride sharing exist in only a subset of these scenarios. Dynamic ride sharing, which provides greater flexibility and convenience, may succeed in some scenarios. Casual and static ride sharing, which has a low cost (free) business model may remain viable in many scenarios.

Inhibitor: identify niche scenarios where incentives can be brought to bear, where dynamic ride sharing provides greater benefits then other mobility measures (such as public transport, static or casual ride sharing schemes).
