While I’d certainly prefer to watch Netflix than actively drive, I’ve still got stuff I need/want to do that I can’t in a car even as a passenger. And it’s just not comfortable for long periods of time. A lot of people get motion sickness staring at a screen in a moving car. Etc.
A lot of people own pickups just because they occasionally want to tow something or move something large. A lot of people own second cars for occasional use. These might become rentals instead when it can affordably just show up at my door in a half hour.
There’s no way to tell how this plays out. There will be some amount of induced demand, there will be some amount of reduction in use. One never knows which will be bigger.
What I do know is traffic deaths kill over 40,000 Americans a year, and driverless cars could potentially get that to 0 or near it, whereas human drivers cannot. I do know we can electrify cars and power them all with renewable energy, not immediately of course, and remove many of the environmental concerns. We can enhance mobility for the elderly and children and mentally disabled who can’t drive.
There’s a strange amount of anti-car propaganda that has gotten people worried about this, but I look forward to a driverless future in which cars are cheap, clean, safe, and available to all.
It’s not propaganda but jumbled concerns which are often poorly expressed. I think the strongest arguments are:
1. Self-driving cars don’t change pollution - even EVs are better for local air quality but still cause massive carbon emissions and unchanged or worse tire particulates, etc. – and may even make it worse locally with the extra mileage from taxi fleets.
2. Self-driving cars only lightly improve congestion, and then only to the extent that they can coordinate and you can ban non-AI drivers from certain chokepoints at certain times. The form factor unavoidably needs far more space per passenger than anything else.
3. Self-driving cars don’t really help with affordability – even if the current prices come closer to parity, that’s a financial stress for many people (e.g. in the region where I live, the average family spends as much on vehicles as they do food).
4. Self-driving safety needs a different relationship with the manufacturer. There are many areas where they can be safer but failures can also be correlated so we really need companies to share liability and have rigorous safety oversight.
As a pedestrian, I’m fairly bullish on the concept given how dangerous the average driver is now compared to 20 years ago but I worry that a lot of politicians are going to ignore the other issues because those require hard choices whereas it’s so compatible with American culture to say you can solve major problems by making an expensive purchase. These shouldn’t be opposing issues, of course, and I’d really like to combine them because autonomous vehicles should soon, if not already, be much better about following speed limits, staying out of bus lanes, etc. Making advanced automatic braking a requirement to enter a city could save thousands of lives every year.
I had half a mind to write a long treatise on why I think we'll only see significant EV adoption if/when cars become driverless, but I'll save it and just go with this. Someone I know was killed last week in a hit and run. She got in a minor car accident, got out to check on it, and a third driver hit her and took off.
When it comes to affordability, economists generally set the economic value of an average American life at ~$10 million, and 40,000 people die from traffic deaths every year. Even if we just look at the numbers, Americans buy about 3 million cars a year. So 40,000 * $10 million divided by 3 million is a savings of over $133k per car, which is far in excess of the average car's lifetime cost. Even a 50% reduction in deaths, which for all I know currently existing driverless cars could achieve, would be the same as making all cars free in terms of average cost.
And even if driverless cars are a total push in every other respect (and I think they'll be much better) 40,000 families a year (and I assume globally, at least 5x that) not losing a wife and mother that way is more than worth whatever we have to do to make it happen.
Stay safe.
That’s not the argument being made. Everyone knows they pollute less per mile – but unfortunately the manufacturing is roughly half of the lifetime pollution from a vehicle.

This matters especially because consumers have been getting heavily marketed into getting massive trucks and SUVs, where the sheer size of the vehicle means the lifetime emissions are greater than a small ICE because the lack of tailpipe emissions can’t make up for that even if it’s powered entirely off of renewables.
That doesn’t mean that we shouldn’t be electrifying the vehicle fleet quickly but it’s buying time on the trip to zero emissions, not a solution. Buses and e-bikes get us much further because they don’t suffer from emissions the inherent inefficiency of automobiles.
It's a free country: people are free to choose to use autonomous cars over ebikes and buses and why wouldn't they? The emissions profile of a personal electric car being unaffordable[0] doesn't pass the sniff test.
[0]Fair economic taxation of externalities - considering current status quo.
I don’t particularly love cars or anything, and would be really happy to not have to have one, but there’s no way I’m going to try to rely on buses or bikes. I value my time, too much for buses and my life, and not being either frozen or covered in sweat too much for any sort of bike.
A car gets you from point A to point B quickly, reliably, comfortably, and with cargo. Nothing else does that, and we are willing to spend a significant portion of our income for it.
I think taxing carbon would be a great way to encourage people to reconsider how they travel, and would expect many people to pick things like those small EVs for urban usage if that became common.
Studies are all over the map but the ones that put it anywhere near 50% are all from China.
No way I can do that and be functional the next day, but if the car could drive itself, I’d probably be going.
If all you pay is the marginal cost then those that live an hour away will pay six times those that live ten minutes away
To the extent that self driving taxi services are cheaper than human driven taxi services, they will also increase use of taxi services.
There's no reason to assume that on the balance people will end up driving less as a result of a technology that makes driving significantly more convenient simply because it might make taxi services somewhat cheaper and therefore potentially might make it easier to not own a car and encourage people to use other modes of transportation for some trips.
