Those are mostly for sprinters and short distance runners as they are higher impact and use running cleats with less cushion then softer distance running shoes. They’re also more likely to fall in events like hurdles and it’s better to land on that then on concrete. Most of the shock that could be absorbed by those tracks could also be absorbed by good running shoes. Most events above a mile take place on the streets.
I didn’t say we could just flip a switch, like you said it will be a long and difficult process, but it will take even longer if we continue to focus on evs as the solution. We could do both at once with unlimited funds and will but we don’t have that, there’s opportunity cost, each dollar we spend on ev subsidies is one not going to projects that can reduce emissions by a lot more like high speed rail and electric bus infrastructure, and currently were spending hundreds of billions of public and private money on evs while almost completely ignoring the other more sustainable solutions. The sustainability movement in the u.s. has very limited funds and public will, and to spend most of that on halfway solutions is short sighted. We need to focus all the resources we can into this because like you said, even with that it would take decades and were running out of time.
I do live in America and have for almost all my life. I have traveled all around this country and know that most of it is extremely car dependent. But my reaction to that is not the problem is so big, we should just do small incremental changes, it’s the problem is so big and were running out of time, we need to do a full 180 right now if I want future generations to not live in a hellscape.
All of this is also just about sustainability, cars are bad for a myriad of other reasons, like the comic says, along with discouraging exercise and exasperating income inequality, and anything that helps people realize how bad they are and denormalizes them is a good thing.
Your right it is a childish problem because a child could think of the solutions you seem to be unable to, instead of cars we could use trains or bicycles, or just walk. Solutions from that fantastical world you lived in before you could drive.
It’s not as if the u.s. doesn’t have anti-bds laws. Also if the conservatives/Republicans were in power in the u.s. like in the u.k. they definitely would be trying something similar to this
The second one relies on it for the number of incidents, which cruise is required to report to the police and in my opinion can be taken as fact. You can try to hide who was at fault for the incident, like they’re doing in the original story, but it’s very unlikely you’ll get away with hiding that an incident happened. If cruise doesn’t report it then the driver or pedestrian that got hit sure as shit will, and they’ve got their branding all over it so they know who to report to. If they report it and cruise gets caught trying to cover it up, they’ll be in deep shit, enough to not make it worth trying to do so. They just lost their license for omitting some footage after a report, imagine what would’ve happened if they didn’t report at all.
That article was written over a year ago and since then a lot has changed. Both waymo and cruise have now been approved for av taxis in San Francisco. This decision seems to not have been motivated by hype but a good track record with less incidents then a human driver. Cruise claims it’s greater than 50% better then a comparable human driver and while that may be just their own flawed study this article also agrees that they’re about even if not better then human drivers.
You’ll probably have to wait a while to buy one though as these are decked out with a larger assortment of sensors compared to a Tesla and probably cost a couple hundred thousand all said and done. They are also specifically trained on the surface streets of San Francisco, so they probably won’t be able to take you on your commute any time soon. Hell id give it another 5 years before their even able to take you to the airport 10 miles south of the city since it would have to get on the freeway. But in this relatively limited problem space they do quite well.
Still better than the hit and run driver who caused all this and hasn’t reported anything.
Your comparing two very different systems. That’s like going to a gas station grabbing some sushi that gets you sick then saying all sushi is dangerous. Teslas have less sensors then the cruise cars and aren’t trained on a contained specific dataset (just San Francisco) like cruise cars have been for over 2 years. For these reasons they are at least even with humans if not safer already and have been approved for self driving in the city while Teslas are far off from even applying.
Yeah but you don’t have to look far to see humans doing way worse with cars. Even in this case the most reckless, irresponsible actor wasn’t the AV, or the company but the person who did the initial hit and run in the first place.
Ideally we’d get all cars off the streets, there use is dangerous in and of itself. But after being around these things for 3 years now I’d take them over the human drivers who I repeatedly see speeding through intersections.
The question isn’t whether they’re infallible, just whether they’re less fallible then humans, which is a far lower bar when it comes to driving.
If these need to be taken off the streets then all cars need to be, which I’m not totally opposed to. These ones have been on the streets in SF for a while and Im more afraid of human drivers then these, they are very cautious and more often then not they’ll err on the side of just stopping. That’s what most of the incidents have been, it just stopping and holding up traffic. Even in this scenario it was a human who did the actual hit and run. I’ve been in them a couple times now and feel safer in them then an Uber most times, they never try and blow through a yellow light cause they want to get to their next ride, they wont even speed.
These also aren’t comparable to Tesla auto pilot. They have way more sensors while Tesla seems to be focused purely on cameras. Teslas are also trying to make a general solution for the whole country whereas these were specifically trained and work in SF. There’s a reason they got approved for full self driving in the city while Tesla hasn’t even applied yet.
Is this like the heart points in the Google fit app?
This is the problem with all trams/streetcars, by definition they run at street level. If anything sf’s are a bit better since they have underground sections. They don’t have an advantage of speed, that can only be gained by getting right of way which is far more expensive and then it’s not really a good comparison to a bus. The main advantage of trams are comfort, capacity and long term cost. Whether that trumps buses flexibility is up to debate.
They usually do it by tunneling through the hills to keep a lower grade ascent. Only the cable cars go up the really steep hills.
The images span is about a mile… I know American fitness standards are low but I think most can walk an eighth of a mile.
Also it’s not housing hundreds of people, as shown in the meme it could house 10s of thousands of it’s not huge lot single family housing, but that’s only if you care about “sound arguments”
