The reason why e-hailing apps have become so popular is because they operate on the model of sharing economy. Uber, for example, is a service where customers can carpool with others, creating a whole lot of positive externalities - less petrol is used, less harmful gases are released into the air and passengers save money. Such service improves vehicleuse efficiency and reduces passenger waiting time and transportation costs. This model should be further promoted to encourage many more private car drivers to join in this sharing-economy model, thereby solving the whole issue around the price of a car ride. It is unreasonable to confine e-hailing service to a high-end niche market, as it goes against the basic principles of carpooling and sharing economy, and will only reduce the market demand for e-hailing service.
