Lamborghini Miura and Mercedes 300SL Gullwing both have it beat IMO

Also, it’s engineers who land robots on other planets, not scientists

Yup. I regularly have to travel flagstaff to Denver, and it would take me over two days to make the trip.

I have another thread in here talking about cost, but just the mileage fees for a trip on a car you own can be a significant percentage of the cost of chartering a plane. If you rent the car it can cost significantly more.

Owning a private rail car is a bit like owning a superyacht; it’s not a particularly fast or practical form of travel but it can be luxurious and fun so people with money do it anyways.

It’s FAR more expensive than vans. For comparison, a fully renovated carriage could cost in the neighborhood of $1M, and Amtrak mileage fees are in the neighborhood of $5/mil. Renting a private car is around $15k per day per car, including mileage fees.

For comparison San Diego to San Francisco is a one day trip by train and about 600 miles. So, you’d be paying in the neighborhood of $2500 for those miles if you own the car, and $15k for charter. You could charter a private turboprop airplane to go that same distance for around $7000. Add in that some private car owners will string multiple cars together, and it can easily exceed the cost of just going by private plane even if you own the cars and charter the plane.

At the end of the day, it’s like having a superyacht—it’s rarely the most affordable or practical route but it is fun and luxurious so rich people do it anyway.

Man you seem to be very negative about this.

I guarantee you that most tourists don’t even leave the rim of the grand canyon at all. They walk around the visitors center for an hour and go home. Go more than 1000’ down from the rim and it’s not particularly crowded at all.

I can’t comment on Europe, like the previous poster—America has far more wide open wilderness than Europe does in general—but if in the USA there are still countless places where you can backpack for days without seeing a single person. There are also plenty of easier hikes with beautiful views that only see a few visitors a day. Just need to put in the footwork to find them. You won’t find them by staying at home and complaining about other hikers.

Well, they are half human so their human half’s genetic memory drives them to swing their arms unnecessarily

And wouldn’t you say the opposite of bearlandia is not-bear-landia?

Male birth control has to be safer and have fewer side effects than letting women carry the burden of birth control.

I mean, I don’t think this is such a high bar to pass.

Pregnancy is bad but I’d argue the consequences of 18 years of unwilling parenthood far outstrips the consequences of 9 months of pregnancy. The consequences for those 18 years impact both parties.

Furthermore, men have almost zero agency of what happens in the case of an unintended pregnancy. A man can’t say, “this would ruin my life, I am going to choose not to have the baby.”

That makes the risk quite high for a man, IMO, and the only way to take agency over that risk is male birth control.

To be fair, right around 50% of us are vehemently opposed to this sort of thing. Far from all America

[–] nBodyProblem@lemmy.world 1 points 5 months ago

Agreed. A plane that can do 200ish knots for a few hours could hit a nice sweet spot for a lot of routes

I can’t comment for their engineering team, but usually open props are more efficient because any reasonably sized duct constrains prop diameter. Increasing prop diameter is the best way to improve efficiency. Ducting a very large diameter prop comes with a large structural and weight penalty.

Generally speaking, the only time ducts buy their way on is when they are also needed for bystander protection.

 
 
 
 
 
 
 

Car communities are always filled with people wanting to know what they need to do to get started with car activities like autocross, track days, or meets. To kick off useful/informative discussion over at /c/ft86@lemmy.world, I decided to write a series of “getting started” guides. I hope they might encourage some people to stop thinking about it, go out, and do fun stuff.

I feel like they might have some interest to the wider car community, so I’ll repost them here with some modifications to generalize anything that is 86/BRZ/FRS specific.

Autocross

What you need:

Autocross is often confused with track days, which is really far from the truth. Autocross is really no harder on a car than any number of normal on-street activities for a sports car. The runs are only ~40 seconds long with tons of cool down time between runs.

However, you do need a car in good working order that will pass tech. This means no bad wheel bearings, suspension that isn’t falling apart, and a properly secured battery. You are also responsible for ensuring you don’t have any major coolant or oil leaks. Nobody likes it when someone oils down the course and runs have to stop to do cleanup.

You also need a helmet if your region doesn’t have loaners. Most do, but it’s a good idea to ask if in doubt.

Nice to haves:

You probably want to bring a tire gauge for adjusting pressures.

Summer tires are good to have because all seasons are prone to chunking when driven hard. You don’t need to buy special autocross tires when just starting out, but if you are on all seasons keep an eye on the heat between runs and be carefully not to overdrive the car.

Bring lots of water, sunscreen, closed toe shoes, and maybe a wide brimmed hat. You will be out working at most events and will get a lot of sun.

A helmet sock is nice to have if you are using a loaner helmet.

Additional prep info:

I’d like to discuss the issue of classing. Basically, don’t mod your car to prep for autocross if you aren’t experienced at the sport. The things that knock you into a higher class can be unintuitive and if you don’t mod with a class in mind it will quickly become impossible to be competitive without huge money outlays.

For example, any aero mod in SCCA classing will knock you into either prepared or xtreme street at minimum. Prepared allows full on racing slicks and stripped out interiors; it is VERY expensive to compete in. Xtreme Street allows unlimited powertrain modifications; in many regions the winners have widebody cars with 3x the stock power levels and it takes a ton of prep to win in that arms race.

It’s usually best to just show up in a stock car for awhile and build for a specific class once you have experience.
