"Worse" was not for people in the vehicle but the people below. After car forced us to be aware of our surrounding when walking, flying car would force us to be aware of the sky too.
Humans have always needed to be aware of their surroundings. Plenty of pedestrians were hit by horse-drawn vehicles before cars were even invented.

What's meaningfully wasteful depends entirely where and when you are, and how plentiful water is locally at the moment.
I don't think so. Just because you're not in a water-stressed place doesn't make you eligible to keep taps open 24/7. This mentality is what brought us to today.
The Great Lakes have 1/5th of the world's freshwater. Absolutely enormous volumes of that water run out the St. Lawrence into the sea, continually, all the time.
I don't have any reason to leave my taps open all the time, and my water is metered so I would pay for such profligacy in money I could put to some useful purpose.
But I can certainly do it without creating any meaningful environmental stress. This would just briefly divert it from its destiny in the Atlantic.

I traveled through Mongolia for a week. Every camp we stayed had a water tank, and water use was extremely constrained. Same for electricity and heat.
Your position is akin to getting power from the first distribution point near a nuclear power plant and saying that electricity is indeed infinite for everyone on the planet.
Just because you don't prepay (but pay as you go) for fresh water doesn't mean that everyone has that luxury. I have shared a couple of maps down there. Maybe you should give them a look about our planet's state.

I suppose, one advantage would be that you can use it while almost asleep, while you need a minimum of mental presence for a shower. So if you wanted, you could: wake up; slump into the bathroom and into this thing; press the button; snooze another 15 minutes while part of your morning routine is being done for (or to) you. Whether this is something you should do is another question... (Also, it might be possible to…
Your vision lacks the ultimate destination: This will replace the bed.

Catastrophical failure would be way worse. Flying is less energy efficient. You need to find cheaper and clean energy source. You need to find a tech that allow to fly quietly. Forcing to make people walk more is better for the society as a whole.
I'm forced to disagree. Catastrophic failure would be a feature not a bug. "Natural selection against stupidity."

Water is by far the most abundant resource on the planet (70+% of earth is water), and we have methods to remove salt and contaminants from almost all of it. We can even turn urine into drinking water. I wouldn’t worry about wasting it. We’ll die from something else long before water becomes an issue.
Water already is an issue in many places. It's expensive and in limited supply because we can't drink salt water and storage, treatment and delivery cost money.

You are right that for able bodied people it's at best a gimmick. But it might be useful for people with limited mobility, who don't want to depend on other people washing them.
Safely getting into and out of it looks very challenging for people with limited mobility. But the article's final photo is of completely different model - far more accessible, far safer, and for "the health care sector".

A nominal water aerator limits water around 5L-6L/min levels. For every minute I don't use the water, I spend approximately two full kettles of water. With every 5L of water I can - Cook 4 servings (~400 grams) of pasta. - Brew 5L of tea/coffee - Water all the plants at home two times. - Possibly wash most of my handwash-only dishes in one go. - etc. So it's not not meaningfully wasteful . However, I can't turn off t…
