I'm not concerned with the price of rides increasing, I'm concerned with the unemployment our country is going to get punched in the face with. Between cab drivers and OTR (truckers), we're going to have a MUCH bigger problem on our hands than we've seen since Detroit collapsed (which was arguably less of an issue since it occurred over a longer period of time).
Uber will run out of money long before we have self-driving cars.
This is a very good point. Also consider that many more people need help with groceries than with luggage.
Heck, with amazon groceries and other similar services, why do they even need to go to the store?
As for "at their home" - if you think that the cross section of elderly people who:
Can't lift their bag into a car.
Travel frequently.
Have no friends or family to help.
Have no neighbors to help.
Don't live in assisted living.
Is enough to sustain the industry, I think you're in for a rude awakening.
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.
