Yeah. they're horrible. Find your local library, they have tons of things going on, usually. Probably have something you might find interesting involving others.
Otherwise, there's plenty of other 3rd spaces, like community centers, or things more directly dedicated to your interests.
Again, hanlon razor applies here, so I don't think you are sponsored by the oil industry, but you repeat their taking points exactly.
While I don’t disagree with the sentiment… the reality is that used evs are a shitty option. What we need to be doing, that would benefit everyone, is building out mass transit, that run 24/7 and at reasonable frequencies.
Yes. Totally the talking points of Big Oil.
Totally.
You’re full of shit.
A quick search, and average EU driving is about 10k km/year.
Being generous here and not using the more-than-double American numbers, you can expect a typical decade-old ev to have lost about 20% of its range, and having had about 200km max range when it was out, for about 160km.
Fine for daily commute, sure. Not fine if the owner ever wants to visit another city, for oh so many reasons. Not like us poors have a life. Nope all we ever do is commute, work, and go home. That’s all life is….
So, ev’s age such that the EV’s die with the batteries. Most the EVs on the used market are teslas* or absolutely at their end of life, as far as value goes-most of the cost of an ev is in those batteries.

(*which there are oh-so-many reasons to not drive, including that Tesla will still be profiting from you, even if you get it used. Because they track the shit out of you driving to train their FSD.)
My first car was a Toyota Tacoma. I miss that thing. The bed was low so you didn’t have to kill your back, too.
And for all those “I use it for my job” types, they’d have more use out of a freaking transit connect.
When SUVs became “family vehicles”, instead of the dick-compensation-machines, marketing said “ahah! Big trucks!” And now big trucks are the dick compensation machines.
the longer you spend at sub orbital speeds, the longer you're spending energy to counter gravity. Building a ramp and lifting it up slowly would only be feasible if you had cheap power to do it. but over all, you're still using most the same amount of energy to get there anyways.
also... if you're going to slow, you'll just fall back down...
So....you're gonna have to define what 'into space" means. 160km is the bare minimum for LEO (its still low enough it'll degrade, but not so low that you can't make a full orbit.) the ISS is still in LEO, and still requires some occasional burns to lift it back into orbit at 400km. To get above the atomosphere so you can (mostly) float endlessly in space, you'd need to go to 1,000km
Pick one. that's how high you need to be.
If you want to just technically reach orbital speeds... you could do that at sea level by going about 7.9 km/s. there's a small problem of air resistance causing you to burn up and, if you somehow survive that, well, here's mountains to go splat into.
If yo wanted to orbit at 160km's amid musk's space junk... that's about 7.8km/s, 400 is about 7.67, and 1000 is about 7.35.
There are some systems that may or may not be viable in the future that don't rely on rockets at all, for example, the launch loop which is basically a cable held up by making it rotate really fast. (yeah. talk about whacky.) This thing, as propose, is 60km high and several thousand km long. The idea is that you lift up a mag train and then that mag train accelerates at a comfy 3g. You then use relatively inexpensive kicker motors to circularize your orbit as you reach apoapsis (aka, the point of an orbit that is furthest away from the body you're orbiting.) This raises (or lowers, depending on which way you're pointed,) periapsis, which is the closest point.
The thing about ramps, though, is that if your rocket car is already accelerating at 3 or whatever g (most modern launches push 3-4g, mostly limited by the squishy payload.)... you don't really need a ramp, and trying to use one anyhow just introduces more inefficiency into the system.
The point of the launch loop is that it gets us off dumping shit loads of CO2 and other greenhouse gasses- it can be powered by nearly any kind of power (though nuclear is the proposed plant,) and the train is accelerated by riding eddy currents off the loop itself.
Edit: there are other, more reasonable methods for a non-rocket launch, but launch loops are basically a ramp. so. there.

.... It hought the INN was another SW memes sub. And like... .this drove me to the darkside....
