This document outlines a proposal for UberCab, a next-generation on-demand car service that uses smartphone apps and GPS technology. Key aspects include:
1) Providing a luxury car service that can be requested with one click and guarantees fast pickup times, unlike traditional taxis.
2) Operating a membership-only model with professional clientele to avoid expensive medallion licenses.
3) Using the latest location-based technologies like geo-aware auto-dispatch to optimize routes and minimize wait times.
