goddamnedtwisto posted:

oh goody another countersteering debate with everyone talking past each other.

to summarise and hopefully save us all the pain:

- it is technically feasible for a bike to turn with solid steering if the front and rear wheels are of different sizes but the radius will be huge, and this effect is absolutely tiny compared to:
- conventional bike geometry means that the front wheel *does* steer into the turn if you lean with body-weight alone but at any decent speed the amount of steering required is absolutely tiny and not really perceptible to the rider
- counter-steering *does not* make the bike turn faster (or rather it does not reduce the radius of a curve that a bike can make). it makes it get to a lean angle suitable for the curve in less time/distance and so *does* allow you to take the entire curve at a higher speed, but constant pressure on the inside bar mid-corner actually pushes you wide (and of course pressure on the outside bar attempting to tighten the curve also pushes you wide because it sits the bike up - this is where the confusion comes in because you can't take a corner at decent speed without countersteering at corner entry and exit, but countersteering is *not* what makes the bike go around the corner, it's what puts the bike in a position to go around the corner
- on a platonic ideal corner and bike you are giving no steering input whatsoever once the bike is turning at the radius you want, but of course this is impossible in the real world

and also to head off the inevitable sidebar - countersteering has almost nothing to do with gyroscopic precession - the effect is there but is absolutely swamped by the much larger effect of pushing the front wheel out of track

thank you for heading off a larger debate, even at the expense of possible funy misunderstanding

yeah it’s weird. they also somehow were chosen to build a Chicago loop to ohaire (airport) transit system, which would be a real, big boy, important route. how it got that far i have no idea but i think it’s since stalled out.

but the Vegas thing is actually happening, they already excavated tunnels and station vaults. the best we can hope for is it’s just an embarrassing and underwhelming boondoggle. hopefully nobody dies when they try to push too many cars through a tunnel too fast at the request of elon. and hopefully it doesn’t “work”, since im emotionally invested in elon’s failure.

yeah elon’s bid came in $10m less than the others. so about $50m vs $60m or something like that.

according to https://techcrunch.com/2020/10/16/elon-musks-las-vegas-loop-might-only-carry-a-fraction-of-the-passengers-it-promised/ about 30% of the contract comes from meeting various levels of traffic handling. they get 10% when they can do 2200 per hour, 3300 per hour, and 4400 per hour. so maybe it really will be cheaper than the other bids (because it sucks and they don’t pay the performance part of the contract and collect some fines).

I really don’t get the Tesla fear mongering either. I don’t have opinions on “autonomous cars” as a whole because Tesla is the only one with a large amount of miles driven semiautonomously. If the measurement of that safety is miles between incidents autopilot seems to be much safer than the us average, at least according to the numbers reported by Tesla. 4.5M miles between crashes with autopilot engaged compared to a US average of 0.5M.

There’s certainly flaws with this logic, maybe most important is that autopilot can only be engaged in lower risk scenarios, but that seems to be changing very soon. Additionally, the types of people who buy Tesla’s may be safer drivers than those who drive Maximas and Malibus, which have the highest MY2017 death rates. So at a minimum the fear mongering seems unsupported, but the consequences of acting on that fear mongering may mean 5-10x more accidents.

There’s a ton of fear mongering around “plowing into pedestrians/children” every thread it’s mentioned in but here’s the euroncap rating on their cheapest car: https://www.euroncap.com/en/results/tesla/model-3/37573

It scores comparably in pedestrian safety to bmw sedans and the test report indicates the cyclist avoidance got full points and the pedestrian avoidance performed well. There’s billions of miles driven...so I just don’t get the cultish hate in the same way I don’t get supporting Trump or not wearing a mask in public in the US.

vegas's situation is so goddamn dumb. the strip is probably the poster child for public transit use like a subway, monorail, or really anything -- a relatively straight, single road, bordered by destinations on all sides. but instead we just get the lovely monorail that goes nowhere and the idiot cartube.

even funnier is that more or less all of the strip casinos started charging for parking, such that the lack of charging for parking became one of the south point's ads for a while. might still be, even. (south point being one of the casinos that's not on the strip but is fairly far south of it)

fun vegas trivia: some parts of the south point still have a "SC" logo, iirc mostly in the parking garage. it used to be called the "south coast" and was part of that family of casinos (gold coast, etc) until it split off for whatever reason


bilking customers is the same reason that the taxi authority was so invested in killing uber and lyft here back in the day. not because those services were lovely (they were) but because it would introduce a competitor to the long-haul grift, where a cabbie would take you from the airport to the strip the "long way". with the central app-based routing uber/lyft the routing made it a lot more noticeable when someone tried to long-haul you (and the pre-paid costs generally prevented it as well)


everyone's loving this city and the only goal they have is to keep being the one that gets to gently caress it.

"That's right. We've evolved."

"I can see that. Cool mutations."





I was thinking about this today, after a Tesla zoomed past me going way too fast for the conditions/surrounding traffic. We have quite a lot of them on the road here now, and it seems to me like at least 50% of the time when I see one, the driver is doing something stupid and/or risky, even by Vancouver standards.

I got to wondering how much of Tesla's increased fatal accident rate is just due to the overlap between high-risk demographics and the kind of people who are likely to drive Teslas. I don't doubt that a good part of it is the car's inherent unreliability, but young techbros with something to prove do not seem like they would be the safest drivers to begin with. I imagine there's also a certain amount of reasoning that goes "but it's the safest car on the road, so it's OK if I take more risks."

i assume it's the usual expensive car = dangerous rear end in a top hat driver thing combined with the fact that tesla straight up encourages and enables incredibly unsafe driving

Unless they're willing to torch capital expenditure levels of cash on a monthly basis at this project, you don't need to worry about whether it will fail.

dozens of cars flying around poorly lit, poorly constructed tunnels while passengers have to climb in and out of these cars only a couple at a time is a taxi service, which is hard enough to run

Wear and tear on a taxi is challenging enough for purpose-built vehicles. Picture all of the craftsmanship problems Desert Tent Car™ Inc has been having with stupidly wealthy people who coddle thir cars, but now they're selling kinda-taxis placed under constant load.
