With Uber, Lyft, and other ride-sharing services, I would say there is more employed in the "move people from A to B" business now than ever before. The mobile apps increased the supply of drivers and captured the market demand for convenient and cheaper rides.

Self-driving would take away a big chunk of that market, but estimates vary on when that becomes a reality. With every major technology improvement, there were massive employment and social shifts. Wars and revolutions were often side effects. However, I don't think the percentage of the population engaged in the taxicab and trucking industries are enough to destabilize society. By its nature, the employees in that business are often transitory. Perhaps there will be legislation to force self-driving vehicles such as taxicabs and commercial trucks to keep a human "driver" to supervise and assist when the vehicle gets into situations outside of its programming.
