Offtopic: that first sentence sounds very weird, I think your syntax got messed up. Use two enters to get a blank line in between. You can't do something on the next line (this is not real markdown). See: https://news.ycombinator.com/formatdoc

This was extremely confusing for me. Why not have both driver and rider in Waze Carpool app...? Or is it for future integration?

I think you're missing Scoop.

Thanks for the shout joncrane :)

I apologize for missing scoop, even though I am regular user of it.

To add to the list and hopefully make it more complete

Scoop : http://takescoop.com

Lyft Shuttle[In beta] : http://lyft.com/shuttle

Uber ExpressPool : https://www.uber.com/ride/express-pool/

I think the ridesharing businesses are making a real difference in optimizing cars usage and helping the environment in the process.

haha if you send me a t-shirt, I will wear it proudly!
