So a user sees a billboard, decides that a hamburger would taste good right now, but is prevented from exiting the freeway because the system running 8k cars per hour knows better. Uh huh.


Opportunity for the helicopter grappling hook concept to be repurposed into food delivery operations.  I keep telling you guys that the concept goes with 150 MPH AI cars like jelly does with peanut butter.

Of course one must wonder how is the issue of having to go to the bathroom solved?  In an emergency simply asking the AI car to find you a public restroom might not be fast enough.  For an answer it seems we must look back to the past:

Further I propose that in the interest of future AI car use we shift clothing to work with the technology instead of against it.  All future clothing should be of Onesie design with velcro pull downs to make using the onboard chemical toilet easier. 

Two separate issues: At 150 MPH, the need for restroom breaks would be far less. If you can get where you are going in 90 minutes, you stop when you get there. At 8000 autonomous vehicles per lane per hour (which almost doesn't happen on trains), you simply program in your rest room stop a few minutes in advance and your car exits and pulls right up to loo.


Sounds great in theory.  Still doesn't account for what happens when what you ate the day prior suddenly isn't agreeing with your stomach.

You are making assumptions about average trip length being the same. More likely average trip duration would be the same with WV commute to DC becoming a new normal

I heard those horror stories happening on NY thruway. No AI needed.

Heh, let's just say I'm glad that not everything on CA 58 east of Barstow is freeway mileage.  Some of those dirt road turnouts came in handy in 2022 when I wasn't feeling well while driving overnight to Las Vegas.  The AI car (and adjacent lane stuff) as proposed in this thread seems to fail to account for similar over the road emergencies.

After all this time, we finally learn the truth: the signature scene in 2001: A Space Odyssey was about a man having a bathroom emergency in one of K12's self-driving cars.

Maybe we can just give everyone a free pack of adult diapers with their 150 mph ai car.

It depends.

I wonder what happens when the lead car in the 8000-platoon at 150 mph has a septic system failure, and the waste spews behind it.

Quote from: tradephoric on December 26, 2024, 01:06:21 PMBump drafting at 200 mph, you travel 293 feet per second.  At roughly 18 feet long about 16 cars can fit in a lane per second.  16 cars*60 seconds*60 minutes = 57,600 cars per hour.  I think that's a pretty safe theoretical max.  8,000 cars per hour is roughly 14% of the theoretical max assuming the pack is traveling at 200mph Superspeedway speeds.

Hopefully you see the problem.
Cars could ignore user inputs that would cause accidents, just like those manual shift modes that prevent you from downshifting so much that you'd damage the engine

I think we've determined based on discussions regarding lane departure and adaptive cruise control that the human driver may prefer to override those features if they end up causing too much discomfort to the driver if they frequently jerk in response to the adjacent traffic. To 'lock out' the driver might give them the impression that there is a malfunction, think stuck accelerator.

It also calls back the spontaneity of cars entering and exiting the highway in general.

This is one of those statements that tells you someone has never written a line of code in their life.

Quote from: Roadgeekteen on December 20, 2024, 10:22:43 PMInstead, we should spend money on high-speed rail around the country. I will not elaborate.
You know what? This idea makes actual sense.
I do think we should still spend money on upgrading roads but a balanced transportation system makes sense. Germany manages to have the world-famous Autobahn and a better transit network than America.

They have density
Parts of the US have density, like the Northeast, California, Florida, the PNW, and the Texas Triangle. We don't need high speed rail between Rapid City and Bismarck.

And yet the HSR line here has a whole bunch of stops planned for non-dense areas.  That corridor should have directed lined between Los Angeles and San Francisco as a proof of concept. 

Yes, I strongly agree.  First they should make the high-speed line between large cities with traffic between them that can fully justify the cost of the line.  Then you can add non-express services later as they are justified.

Idea that with the small gap, there is not enough time to get significant speed differential. So the crash can be relatively non violent without major damages.
No, I really, really wanna come to a full stop on the freeway. Like, now you're pushing into me but now you're getting slowed down, so now you've got the person behind you pushing against your rear bumper. Also, it's causing your forward motion to shift side to side, so now you brush up against the car in the next lane over, and that causes a spin out and the collisions now become a pileup.
