DIYcity Challenge #2

DIYcity Challenge #2: Conceive of a grassroots ridesharing system that can overcome the problems inherent in ridesharing and achieve critical mass.

Ridesharing sounds like such a great idea - everyone teaming up, riding 2, 3 or 4 to a car to get where they're going together. Fewer cars on the road, less CO2 created, everyone happy. But the reality is that lots of ridesharing systems have been designed but none have really caught on to any appreciable amount.

Why is this? There are lots of reasons. Flexibility, reliability, safety, critical mass challenges and more all conspire to prevent rideshare systems from taking off.

Here on DIYcity we've already had a pretty good discussion on building a ridesharing app that works. But nobody has nailed it just right yet. Can you?

Submit your idea for the killer ridesharing app to diy@diycity.org.

You don't actually have to build anything for this Challenge, just write a concise proposal and it will be posted to the site.

If you do actually build something then wow, that's really cool, please submit it here.
