Cool idea. A couple of good points made in the comments: 1. Flexible hours 2. Privacy/Safety issues The first point is common to all ride-share including mass-transit. I think you need to consider a mobile strategy that addresses a scenario like "I'm ready to go. Anyone going my way?" or "I'm headed out. Anyone need a ride?" Privacy/Safety is implicit but important. You partly address that via gender specification but it needs to go further like "I'm a girl is only willing to share with other girls". Anyway, a nice start. If you're serious then there is much work ahead.
