I wish we could somehow make a huge self-driving car that could link up to other cars. Maybe we could even have specialized roads for them where they can go on rails or something to help conserve the car’s battery and even recharge it.

yes, and we could add one more rail to make it not need a battery at all. I think that would be a nice addition, as batteries are expensive…
Maybe we could even make suspend cables in the air to power them. Seems cheaper than one more rail.
Better for the environment, too!
I love re-deriving the train with people as a thought experiment
I love when carbrains do it themselves 😂
🎵 Deriving that train, high on cocaine
Yeah I often imagine something like a self driving podbike "robotaxi". It weights ~65kg and needs a tiny fraction of the energy to reach 50kmh (30mph) in a city. Or better a longer version with 2 seats facing each other (for two people or for shopping bags).
For longer travels you could even have "roll-on/roll-off" trains so you could get in from your home, roll on and then roll off while staying in a comfortable compartment.
I'd love to know how a "robotaxi train" would compare with public transport in terms of embodied and expended energy. My guess is that it's rather close and would be much more popular, and easier to maximize utilization, hence more easy to make real.
I mean... I know that your are implying using trains... But trains don't work on all situations, and something like you say that is a middle ground but that doesn't depend on rails which is basically the limitating factor in some cases due the height differences or other related issues wouldn't be that bad.
My city used to have 19 tramlines and 4 trolleys a century ago
Now we have zero and we are building one using a private-public funding-scheme.
There've been accusation of corruptions. The tramline is still being built (almost 10 years now).
That's a little too long for laying tracks and electrical lines.
Although even in the Italian city I take for reference, Bologna, construction of line 1 started in 2023 and is expected to ~~finish~~ complete in 2026. If it was a private company with no external contract awarding, it sure wouldn't take this long.
Belgian here. Our ex PM's two brothers have been caught printing fake money in connection with the cosa nostra. It may help to explain our tenancies to have never ending public work. Embezzlement doesn't help not to overrun delays and budget.
Rail infrastructure projects can take decades. Land acquisition alone can take 10 years.
These project can be sped up massively if there is prior land available to use as rail. For example a road or street, too bad we don't have those.
This is after planning and awarding. It's 3 years just for phisical construction.
I'd ask if you're in Ottawa but it could probably be any city in Canada or the US 🙃
Missed. Western europe.
op inventing "not driving"
Now that's a meme!
I really hope that's not true. I am not sure about state of self-driving cars, but there still should be a conscious person in the front seat.
Oh yes it is true, there is a video of it. And yeah it's like that, it requires som attention from the driver but people bypass security stuff they have or simply do the bare minimum so the auto driving continues. At the end they break the law regardless but it allows them this crazy stuff.
The only exceptions are some cars that's re completely driverless and act as taxis, I think Waymo and google has them as those are allowed to have blind people or people without a license and people usually are on back seats or similar.

At this point bus is better
No country in the world currently allows the driver to focus attention on something else.
If you buy a very expensive Mercedes with a subscription, and drive it at a very specific speed on a few very specific stretches of road in Germany, you can.
