I'd much rather all of the resources that are going into autonomous cars was instead going into proper public transit infrastructure. Cars are so hopelessly space and energy inefficient, and I hate driving them. If I could get around by bus, light rail, bike, and all of the wasted city space devoted to parking could be turned into more housing and amenities, that would be great. I think it would be meaningful to also…

Those (rare) occasions are when you rent a car. You can do it many times per year before it becomes a financially worse option.

Rental scooters/bikes cover last mile service very well in my experience. I use transit a great deal more than I would if I had to walk so much on either end of the trip.
Americans would rather die than give up their air conditioned bubbles on wheels. I've wondered why someone hasn't tried manufacturing an enclosed go kart with AC and enough trunk space for a few groceries.
Because they are completely unsafe against a twice-the-height, multi-ton Ford pickup truck.
I have a feeling that once everything goes EV and autopilot, they will start phasing out regular cars or will make it more difficult to obtain the license.
And it'll negatively impact all but the upper classes. Automakers would rather everyone use their autopilot taxi services for the higher profit margins, so autopilot EVs will be prohibitively expensive to outright buy.

It is, at least in a place like LA. Fares are like less than 10% the actual total cost of an average bus ride. https://www.reddit.com/r/LAMetro/comments/1orftnt/should_you... Now if you’re ONLY serving high density and high passenger volume times, buses are incredible.
Is your point that busses aren't profitable? Why do they need to be? I am sure if you did the math, having the occasional empty bus does not hold a candle to the amount of dead mass being dragged along in single-occupant cars. The wear-and-tear on the road from the sheer volume of cars alone makes them cost more to us as a society than busses. So regardless of density and passenger volume, busses are incredible.
That doesn't really math, because axle weight is a large factor in road wear. There's details and it doesn't always apply, but the commonly used rule of thumb is that "road wear increases in proportion to the fourth power of its axle load."
If a transit bus weighs at least 25000 lbs and has two axles [2] and a F-150 has an average weight of 5000 lbs with two axles [3], you get a lot more road wear from putting a bunch of people on a bus compared to all of them driving their f-150s by themselves. The power rule says the wear from one bus is equivalent to 625 F-150s. Although if people rode around in classic Beetles (~ 2000 lbs), there'd be even less road wear, and things would be a lot groovier.

Fatality data is extremely skewed. 44% of drivers aren't using a seatbelt, 29% are speeding related, I recall alcohol involvement being about 30%, though it's not listed in the link I checked. About 20% of automobile fatalities aren't in cars but are pedestrians or bicyclists struck by cars (add another 16% if you want to include motorcyclists, though only half of which involve another vehicle). I recall the percenta…

Great, so when a deer jumps into the middle of the highway the size of the ensuing pileup is twenty times larger. I don't particularly think we should use technology to push efficiency to the point where a mechanical failure, a material failure, or an unexpected object cause much larger scale catastrophes than exist today. Why not aim for the same distance between cars and twenty times more safety instead?
Because traffic volume. Autonomous cars won't panic and cause pileups.
It's to assume that every single thing that could break, will break, and design enough resiliency in that you have to stack up as many failures as possible before things truly go off the rails.
So to do this without killing people, you add the new systems with the same safety thresholds, then gather quite a few years of statistics, then, slowly let things become more efficient if that's both warranted by data and also warranted by simulation of events that you do not yet have data for.
Skipping steps in this because you want to put more cars on the road immediately is foolish and dangerous.

> "The majority of drivers are good, but some drivers are really bad." I take issue with this. The majority of drivers are "mostly fine as long as circumstances are favorable", not "good". People for the most part do not even know about the concept of defensive driving let alone practice it. Even the best people are fundamentally complacent in basically everything they do. They zone out sometimes, they get too close,…
The mean driver in the context of the USA driving environment is shockingly safe. Being safer than even the mean human driver in the USA is hard and takes a shocking amount of data to verify. Anybody downplaying it as "lol humans are so unsafe" to argue the problem feels easy to solve or can be solved by the end of the year with a little bit of elbow grease is utterly clueless.

It has been, from the start and even before FSD had any basis in reality and was just sci-fi stories, obvious that FSD would eventually get here. The only question has been when. We clearly aren't there yet but it is pretty obvious we aren't as far away as the naysayers make out. I want FSD, but I want it on consumer terms. Safety is only one aspect and it is the one constantly brought up. It is important, but in the…
Most drivers take absurd risks that negate any possible skill advantage.
