The infamous Randal O'Tool claims that driverless cars will render HSR obsolete:

Amtrak often brags that it carries more people than the airlines carry between New York and Washington, which are 230 miles apart. But it admits that it really has only 6 percent of the intercity travel market in the Northeast Corridor, with airlines carrying about 5 percent and the other 89 percent going by highway.

The coronavirus has increased people’s willingness to take long auto trips as an alternative to mass transportation. At the same time, driver‐​assist systems such as adaptive cruise control are making driving less stressful and increasing people’s tolerance for such long trips. With the livery service Waymo having self‐​driving cars for hire in the Phoenix area and Ford, GM, and Tesla working hard to catch up, the time‐​cost of auto travel is likely to sharply decline before the United States can build much of a high‐​speed rail network...

A lot will happen in two or more decades that could completely nullify the claimed benefits of high‐​speed rail. The pandemic is likely to reduce people’s eagerness to use various forms of mass transportation even after most people are vaccinated. Driverless cars will reduce the cost of travel time because people will be able to work, socialize, or enjoy entertainment while they travel in personal vehicles. Electric aircraft could reduce the dollar and environmental cost of short‐​distance air travel. These and other uncertainties make big‐​budget, high‐​risk projects even less likely to succeed.

To go off topic, IDK why Amtrak has less of a market share over the NE Corridor than car travel, so please enlighten me on why, and also I'd like to know what is an optimal market share for rail on the same corridor. Here is Randal's source, which AFAIK doesn't explain the methodology of the 5% market share figure that Amtrak has.

That aside, I think that Randal massively downplays the issues with getting self-driving cars to work. You still need to implement additional infrastructure (e.g. V2I communication) to fully accomodate self-driving cars, and the ones we do have only work under very ideal and controlled conditions. The issues with hacking and the ethics of autonomous cars also mean that the time it will take to solve these issues will be longer than Randal thinks.

He also ignores that while pandemics can cause people to be wary of transit, this usually subsides in the long run as people adapt to the pathogen and find cures, and if people are going to socialise in a car, they will run into the problem of pathogens if they don't socialise via video calls. And this isn't accounting for the inherent inefficiencies of battery electric aircraft due to their pitiful range, low capacity, poor power to weight ratio, and risks of in flight fires due to their batteries. This means they will cost more to run than current planes, and use more energy per Pkm and passenger than HSR.

This also ignores that driver assists such as adaptive cruise control still require the driver to be alert to take the wheel at a moment's notice, and that Randal is merely assuming that this will significantly increase the distances people are willing to drive based on his gut assumptions and projection without any hard data. Driving long distances is still stressful for a whole host of other reasons (e.g. motion sickness or the inherent nervousness of having to take control at a moment's notice) to render alternatives desirable.

But even if driverless cars do become viable, this won't mean HSR will be obsolete as induced demand will still be a problem with self-driving cars owing to their inferior capacity and slower speed.

I want to make a series of posts going up against common arguments against HSR, which I think Randal's article provides in abundance, so I can learn through mythbusting. What are your counterarguments against his arguments?
