Taxis are the other option that currently exists in these places, and autonomous taxis would have to offer something more than human driven taxis currently do.
Greatly reduced cost, reduced pickup times, wider service
Agreed that the cost will have a huge impact. But expecting costs below Uber, when Uber is already kept artificially low by venture capital funds seems like a bit of a reach to me.
Drivers are the single highest cost
Then gas
Then vehicle expenses (maintenance, depreciation)
And finally the platform (tech, advertising etc)
If you compare Uber costs between a country with a high labor cost and a low labor costs, there's an order of magnitude difference in price the customer pays. Removing the labor means any country can experience this order of magnitude difference.
Then you have lower fueling costs because they're electric. Lower maintenance costs because their electric, better utilization because they are not limited by driver shifts and lower advertising costs because your service is cheaper and naturally attracts more demand.
Transitioning from single occupant vehicles to multi occupant vehicles would be impactful. It could also have happened at any time in the last 50+ years with human drivers. Mass transit, car pooling, etc are pretty much plateued. An autonomous driver doesn't change much of anything in that regard. A person that doesn't want to carpool now isn't going to be likely to want to carpool in an autonomous future because it's not about what's piloting the vehicle that matters for most people in these cases.
Correct, it's about convince, cost and reliability. And that's what's different about autonomous transportation vs the existing modes. The inconvenience of car pooling is removed. When you are ready a car will be ready for you.
Regular taxis can be called for this purpose right now. Perhaps people would feel safer without a human, but there may be other safety concerns with sending your vulnerable kid or elderly parent off in an unmanned "soft target" too.
For low value events current Taxi pricing doesn't make sense. It's an easy decision today when it's $50 for a return trip to soccer practice vs drive my son and myself. At sub $5 for a return trip driving both of us becomes a whole lot less appealing.
This also seems like it could also lead to more miles traveled and less efficient overall transportation system (like Ender mentioned above) if people don't have to travel together as much. Above, you pointed out the importance of traveling together rather than individually, and here you seem to be pointing out a potential advantage of autonomous vehicles is that they'd allow more traveling alone?
Now taking my example above about soccer practice. 15 kids per team today means 15 parents and 15 children travelling to practice in 15 cars.
Where autonomous transport as a service is ubiquitous, we have 15 children requesting a ride. Car 1 picks up my son and on the way it see child 2 is ready and close by, does a minor detour, picks them up continues on its way, the child 3 is ready and on the route so stops and picks them up then delivers 3 kids to practice using one vehicle.
So now instead of 15 cars we have 5 cars to fulfill this transportation need.
That's 66% less traffic. Now the ease of transport will create more travel (I hope it does especially for the elderly), but the savings from shared transport means there is room for massive growth before we get anywhere near the capacity of the alternative we have today.
If you're a for-profit corporation, why would you waste money and increase wear/tear on your vehicles by driving long distances without passengers? They only make money when paying passengers are on board, so maximizing those times seems critical to becoming financially viable. It would also eliminate time spent in travel, so you could service your customers more quickly. Unless charging the cars in dense locations is wildly more expensive, I think it makes more sense to charge them near the most potential customers and minimize time spent driving around empty without a paying customer.
It's not long distances. Being just a couple of miles outside a city center gets you access to locations with significantly lower costs. The fleet operators will know the maths and find the most optimal locations.
