When driving on the highway recently, I noticed a standard governmental sign which had a 1-800 number to call for ride sharing.<p>Your post made me think of this, so I did some quick googling of my state and the surrounding states. It seems all of them have ridesharing programs and regulations to promote ridesharing to some degree.<p>Of course these are not sophisticated technological platforms with mobile apps. Personally I was intrigued by the possibilities for user experience... what would it be like to get a ride by calling one of these phone numbers?
