What if we had one BIG self driving car that dozens of people could comfortablely sit inside while traveling on a shared route?

We could have multiple vehicles traveling that same route so you're almost always assured a ride without waiting long. And as were saving a lot of money with predictable road wear, less pollution and less accidents, we could probably make the rides very affordable, if not free. Last thought, kind of out there , but we could even have one person sit at the front of the bus and look out a window - If they saw a child, animal or some other potential issue on the road ahead, they could see it well ahead of time and hit some sort of hand or foot button that slows the vehicle to a stop temporarily so there aren't any software related accidents from the self driving vehicle that result in injury or loss of life.

It will be like an uber... But for all of US. We'll call it UBUS!

That's actually...kinda genius. It's not just fresh thinking: it's a scalable and green solution to a real problem. I think you could really make a difference with this idea. Would you like to work out some ways we can make life worse for the working class while we implement it?

[–] xavier666@lemmy.umucat.day 3 points 1 day ago (1 children)

Green solution? That sounds like communism

It’s a niche idea from a small European nation, but have you tried having the trains late 2/3 of the time?

I just can’t get you out of my head, boy your mechanical phrasing and can-do enthusiasm are all I think about

Theres an entire unionized industry of train operators that has a problem with this statement.

[–] tias@discuss.tchncs.de 20 points 2 days ago* (last edited 2 days ago) (2 children)

Up until very recently all train route planning in Sweden was done manually with huge sheets of paper and rulers. Scheduling trains is a very hard problem due to the inability for one train to pass another in many places and the constantly high congestion. Any change in the schedule affects basically the entire rail network.

In computer science it belongs to the class of "NP-hard" problems which are intractable to solve optimally. There are various approximate methods that can be employed to get something that's almost always good enough.

Just because it is a hard problem, it doesn't mean it is easier to do with paper and rulers than with algorithms. So the problem being "hard" should be unrelated to Sweden being behind the times.

[–] ryathal@sh.itjust.works 1 points 2 days ago

The problem with train scheduling is that computers don't just make it better. There's a very real chance computers could make it worse or result in approximately the same outcome but not require millions in investment into a new system.

[–] kbobabob@lemmy.dbzer0.com 4 points 2 days ago

I'm having trouble understanding how that relates to the statement about train operators, the ones actually driving the trains because most trains are not autonomous.

[–] jubilationtcornpone@sh.itjust.works 2 points 2 days ago (3 children)

Hold up. This gives me an even better idea. What if, and this is totally hypothetical, but instead of self driving cars, we used trains to transport people?

The train could even theoretically transport a whole bunch of people at one time.

Holy shit. I think we are really on to something here.

The problem with this is that they don't solve the same problem.

I use the train for almost all my transportation, trains are amazing.

However, the train doesn't bring me to my front door. The train doesn't bring me to my exact destination.

A self-driving car would save me at least 45 minutes during my commutes (one way), purely because of the flexibility.

[–] ParadoxSeahorse@lemmy.world 0 points 15 hours ago (1 children)

Literally buses?

If you have volume/demand problems:

Buses not frequent enough
Bus stop is not close enough
Buses take a circuitous route / take too long

This will naturally increase the more people use them. So the only limiting factor is you, your family, neighbours etc.

[–] AliOski@feddit.nl 0 points 13 hours ago

Thought about the limiting factor called "workforce"?

[–] raspberriesareyummy@lemmy.world 4 points 1 day ago (1 children)

A ~~self-driving~~ car would save me at least 45 minutes during my commutes (one way), purely because of the flexibility.

Fixed that for you. I don't see how "self-driving" would be 45 minutes faster.

[–] AliOski@feddit.nl 1 points 1 day ago (1 children)

True, but that requires me having a drivers license + requires me driving. We are talking about the comparison to train commutes and the usefulness of self-driving technology. I don't drive the train.

[–] raspberriesareyummy@lemmy.world 1 points 1 day ago (6 children)

You used the self-driving bit saving you time as an argument in favor of self-driving cars, hence the correction. The time save has nothing to do with who operates the car (unless it's a F1 driver).

The problem is that this whole debate is poisoned. Self-driving cars are not, and will likely never be safe. They can be safer on average than human drivers, it's just that other people will die in accidents than those killed by reckless drivers. The ones dying will die due to software errors / profit calculations and the likes. As such, promoting self-driving without a mechanical guiding control (as in railways) is highly unethical.

It might be possible to overcome the technological challenges of safe self-driving, but humankind as a whole is too selfish and profit-driven to ever reach a point where that kind of research will even be funded with any meaningful budget. That's my prediction.

A real self driving car would increase your commute because it would be able to transport children, dogs, sandwiches etc and the overall effect would be a like 30%+ increase in traffic as people buy or rent more self driving trips for people and objects normally not able to rent rides.

The effect would be analogous to "Jevon's Paradox" where more efficiency increases demand.

[–] Jiral@lemmy.world 7 points 2 days ago* (last edited 2 days ago) (1 children)

A city built for cars (no matter if "self driving" or not) has to be built much more spread out. Distances for everything multiply. At the same time that spread out infrastructure leads to heavily mono-directional traffic, making rush hour load much worse.

That is why people in car only cities aren't any faster than cities well designed for public transit. Yes, heavy rail does not cut it alone, that is why there is also light rail, bus lines etc. With all of that, you can get anywhere you need to go, in places that are not primarily or exclusively built for the car.

[–] AliOski@feddit.nl 1 points 1 day ago (1 children)

Who said car-only? I said that self-driving cars and trains/buses/subway do not solve the same problem. They can coexist just like how they do now.

The only thing this technology does is allowing commute time to become more productive and allowing more automatization for a job that always has shortage (think of bus drivers). If self-driving technology would become sufficiently good, the bus in my village could drive 4 times an hour, purely because there is no bus-driver necessary.

Also, things like traffic jams are supposed to become rarer too with autonomous vehicles, because all those cars are supposed to coordinate with each other. You ever realized that many traffic jams could be solved if everybody would start driving at the exact same speed at the exact same moment, instead of accelerating, slowing down, accelerating, slowing down. This is all because of human reaction time and the lack of coordination between vehicles. Traffic accidents are also supposed to go down.

[–] Jiral@lemmy.world 1 points 1 day ago

The car share can be replaced with self driving cars, however if you make self driving cars more attractive than cars now, you'll shift the balance and are heading towards more car centric and therefore more hostile and less attractive places again.

It is a nice fairy tale hat self driving cars are more space efficient. Real service patterns have shown that they fill up road infrastructure more than regular cars as they will do either fill up trips or need to drive everything twice. Also, making use of these fancy advantages (higher speeds, shorter breaking distance, dynamic crissings without traffic lights) make roads much more pedstrian hostile, more highway like.

[–] VitoRobles@lemmy.today 4 points 2 days ago

After visiting Tokyo, I'm convinced that both can exist. Trains take 95% of the travel and the 5% of the time you need to be someplace specific, car it is.

As for to your door... I was a 10 minute walk to every single destination I needed.

[–] wezzzy@lemmy.blahaj.zone 7 points 2 days ago (1 children)

Better train infatructure plus busses and metrolines will help with this problem

[–] AliOski@feddit.nl 5 points 2 days ago (2 children)

I don't live in the USA, I live in the Netherlands, infrastructure here is very good, public transport-wise too. It's just that a train can't go to every little village that exists. There is a bus, but it only comes and goes once an hour (which is entirely reasonable for my village), which severely affects the travel time.

[–] wezzzy@lemmy.blahaj.zone 2 points 2 days ago (8 children)

Ns is wel tof ja maar het kan altijd beter en self driving cars gaan dit probleem niet fixen je kan beter de fiets of een normalen auto pakken en met beteren aansluitingen hoef je geen uur te wachten

And self driving cars will do nothing to change anything. I you push for them, more than for cars currently, cities in the Netherlands will be much worse places and traffic will get much worse as well.

Cars are of course part of the mobility equation, especially in rural regions with small settlements. 1 hour connections can still be perfectly fine for commuting but it can only be a supporting service there. The story is completely different one as soon as you get anywhere close to any major city. In the Netherlands, most people live in such locations.
