Well duh. Anything less than a full white paper would be oversimplified.
Why do you think that more people will be flying in 10 years? US population is growing at a rate of less than 1% and that is likely to decrease. For your argument to work then autonomous vehicles will need to steal fewer customers than the airlines can gain. That does not seem likely. Domestic demand growth is somewhere in the 3-5% area now. I'm sure that FSD can steal more than a few percent of customers.
Stats: Air Travel Demand Growth Slows to 5.5%
This is purely a thought exercise and I'm hardly offended by people seeing it differently. Consider this, when the internet was in it's infancy, how many saw it and thought "this is going to put retail stores out of business" or "this is going to kill broadcast TV"? Very few (zero?). It's extremely likely that we are missing similar huge disruptions that are destined to occur.
Mobility will continue to increase over time. People will have more choices. But this doesn't mean domestic air travel will decrease.
Autonomous cars will be more convenient for shorter travel distances (ie., under 6 or 7 hours of driving). But plane travel will still be attractive for a lot of people when travel distance is longer than 6-7 hours of driving.
For example, if I had a choice:
1. I could take an autonomous car from San Diego to San Jose and it would take 8-9 hours
or
2. I could drive 15 minutes to SD airport, wait 45 minutes for my flight, take 1 hour flight to SJ airport and arrive.
I would choose #2 all day, every day.
Also, think about in 10 years, will more people or less people in the U.S. be flying into southern california to tour the sites?
