I have driven to Longview twice from DFW airport, i moved from Tyler to Dallas. My opinion is that unless the demand gets up a little, uber won't likely come there. Even in tyler uber is in selected areas
The city council had looked into it and voted to approve it, but the City of Longview wants to implement a system to track TFH drivers similar to what Houston has. Uber turned their nose up at it and that's been about it.
