Rural version of Uber (Highway of Tears)

I just finished reading (at cbc.ca) about the lack of public transportation along the Highway of Tears in Northern BC. Women are forced to hitch-hike, which is dangerous. Starting a shuttle bus would be costly, since the highway is over 700 kms. long. Why doesn't someone start a rural version of Uber? Both drivers (anyone can be a driver) and passengers must have smartphones and PayPal or credit card accounts. In case a driver or passenger commits a robbery or assaults the other party, the police can easily track down the perp, since the perp's ID is in the system.
