And of course all shit electric cars are all automatic. It's part of the NWO agenda. They want to force us all into electric, automatic cars, Over my dead body! A car that does not produce smelly fumes when driving is not a real car. What I am supposed to smell when walking in the city? Air? Fucking dumb. On top of that they make no sound! There's nothing to tune up to make my car sound like a racing machine. How I'm supposed to let everyone know I have a small dick if I can't rev my engine all the time? Not to mention electric cars don't emit CO2 so I can't lock myself in a garage with the engine running and kill myself when I realize that no one is impressed by my car and my dick is still tiny. Absurd!

I've literally seen people post that they'd consider going electric if only it had an engine sound. Seriously, people who are old enough to have a drivers license want their car to go wroom wroom.

I get it. It's the same reason all cars have a steering wheel, despite it being the most dangerous part of the interior. Joysticks just don't give the same feel as when the captain steers the boat over the seven seas.

Wroom wroom, steer steer, wroooom, change gear while turning, push pedal, wroom wroom.

[-] jukibom@lemmy.world 52 points 1 year ago

Steering wheels are enormous because that allows fine grain control, which you need at higher speeds. Switching lane at 70mph requires only very slight movement but turning the car around in a street you can go full lock.

A joystick would be fucking TERRIFYINGLY stupid lmao

[-] filcuk@lemmy.zip 9 points 1 year ago* (last edited 1 year ago)

Some vehicles use steering by wire, which uses motors for i/o. This allows for steering sensitivity adjustments based on speed or even* preference.

[-] jukibom@lemmy.world 7 points 1 year ago

True, but sensitivity is only half the story - the direct feedback of a wheel cannot be overstated

[-] filcuk@lemmy.zip 4 points 1 year ago

You're right, but that should be part of the system.
There is virtually no noticeable lag.
The same technology is used by F1 vehicles, for example.

[-] jukibom@lemmy.world 4 points 1 year ago

Not lag, physical pushback from the wheels

[-] hglman@lemmy.ml 4 points 1 year ago

Fundamentally a joystick is a device that gives input in 2 dimensions, while steering a car is a 1 dimensional input.

[-] wieson@lemmy.world 3 points 1 year ago

But the wheels only have one degree of freedom...

[-] wandermind@sopuli.xyz 7 points 1 year ago

I think that's what they're pointing out, that a joystick has too many dimensions.

[-] hglman@lemmy.ml 2 points 1 year ago

Just like the wheels on the car.

I mean the wheel is definitely the best control mechanism for driving... whether or not it's dangerous, there's a reason the best sim racers use wheels and not controllers and it's that they provide vastly more control. So nice argument except it's all based on a false claim that joysticks are better lmaoooo

I was extraordinarily glad to have a wheel when my power steering failed and found myself having to turn the car using the strength of my arms and the mechanical leverage of the wheel. A joystick would've made the vehicle literally impossible to steer.

[-] ObviouslyNotBanana@lemmy.world 4 points 1 year ago

It'd have to be a long joystick.

[-] Sorgan71@lemmy.world 1 points 1 year ago

thats what she said

[-] axsyse@lemmy.sdf.org 5 points 1 year ago

I'll just leave this here. In short: a guy wrote a physics engine to simulate any combustion engine, and then further got it working with an electric motor so electric motors can use a simulated vroom vroom

I've literally seen people post that they'd consider going electric if only it had an engine sound.

In many regions now it's actually mandated that EVs make additional noise when moving at low speeds (less than 40km/h or so). There were concerns that quiet vehicles would have more pedestrian accidents.

[-] eco_game@discuss.tchncs.de 1 points 1 year ago

There actually is an EV with engine sounds and a "manual transmission" from Toyota. According to ArsTechnica, it's supposed to be pretty good:

They aren't, really. They don't actually change gears, if you want to go backwards you spin the motor backwards.

Hilariously, jump starting EVs is a thing if the 12V battery dies. And no, you can't roll start them.

[-] bitwaba@lemmy.world 10 points 1 year ago

And no, you can’t roll start them.

I imagine you "can", it's just not very effective. Like, if they allowed you to switch it to regenerative breaking and let it roll down a hill. The problem is you can't get out any more energy than you put in. So if the battery is dead and you roll down the hill you won't be able to rull any farther up the other side than you started (even less when you factor in mechanical -> electrical -> mechanical. You'd probably better off putting it in neutral [if that's a thing for electric cars] and just let it roll)

[-] zurohki@aussie.zone 21 points 1 year ago* (last edited 1 year ago)

No, you actually can't.

For safety reasons, the 400V main battery isn't hardwired to the car. There's a couple of contactors powered by the 12V battery that connect it to the car.

If your 12V battery dies, the contactors open and the car is completely dead. You have to jump it or replace the 12V battery, then the contactors pull in, then the main battery can start charging the 12V.

Even plugging it in doesn't work - the car won't take a charge if the electronics are dead.

If the main battery is dead but the 12V hasn't died yet, you can try regenning down a hill or plugging in or whatever. But if you lose the 12V, the car's bricked.

It's set up that way so that first responders can get to an accident, pop the hood, cut the 12V and then start cutting you out of the wreckage without worrying about high voltage cables.

[-] ObviouslyNotBanana@lemmy.world 6 points 1 year ago

just bridge them with a screw driver

[-] bitwaba@lemmy.world 1 points 1 year ago

Yeah, obviously there's technical reasons why. I was just approaching the problem theoretically. And then showing why the theory is stupid. It makes sense that they would implement other things for safety, especially if avoiding them only enabled a completely useless solution to a dead battery.

[-] ObviouslyNotBanana@lemmy.world 8 points 1 year ago

We just need to make all roads go downhill

[-] UltraMagnus0001@lemmy.world 5 points 1 year ago

Some have multiple speeds. I think the Porsche has 2 speeds for quick acceleration.

[-] axsyse@lemmy.sdf.org 5 points 1 year ago* (last edited 1 year ago)

tl;dr: my PHEV does change gears when in EV mode, as weird as it sounds

So, I drive a Hyundai Ioniq Plug-in Hybrid EV (PHEV). It's a hybrid with a larger battery so you can plug it in and drive fully-EV on the battery for about 30 miles/50 kilometers or so. The freaky thing is that the EV motor is connected to the transmission, so it does switch gears sometimes and you can feel it when it does. Even freakier is that this also applies to regenerative braking: when you slow down from a high speed, you can sometimes feel it switching gears while you brake. That all isn't too bad since it's got a dual-clutch transmission and so it switches gears pretty quickly, but it can still be a bit freaky at times.

Additionally: there are some people who have converted antique cars to EVs, but to save money they didn't touch the transmission and instead elected only to replace the engine. They still have manual transmissions in them, though I suppose you could probably just find a suitable gear to leave them on 100% of them time. Still, you can, in principle, switch gears on them.

[-] azertyfun@sh.itjust.works 4 points 1 year ago* (last edited 1 year ago)

Typically I've seen people keep their car in 2nd (or reverse IIRC? That way your controller doesn't have to support reverse and you don't have to put in a new switch on the dash) in electric swaps. Also you don't use the clutch pedal to start, only to change gears, which is a bit freaky when you're not used to it.

On the highway there might be value in switching to a higher gear though, torque/efficiency curves aren't perfectly flat even on electric motors. I would be curious to know what gains would be had on a modern electric platform like an ID.3 if one was to put in a cheap two or three gears sequential/manual transmission (for all I know the efficiency gains would not offset the additional losses from the clutch and gearbox, and even if they are some gains I'm sure that they do not make up for the inconvenience/lack of comfort of a MT).

[-] doofer_name@feddit.de 11 points 1 year ago

Over my dead body!

Be careful now. The German car and American gun industry might listen and team up.

[-] creditCrazy@lemmy.world 2 points 1 year ago

Honestly the only issue I have with electric car sound, is that in the country side animals, listin for your engine. So silent electric cars make it all the more likely that your gonna hit a bear. I'm not even asking for them to be deafeningly loud. Other than that my only problem with electric cars in general, is that they are soo overall boring. The Tesla models are just generic car design smoothed over. At least the Prius has a neat double rear windshield. Honestly the only electric car I've been thinking of getting, are those new 2cevs that are being reproduced, but electric. The only fun cool cars being made today are Supras and Miatas. Everything made in America just looks like a blow up car thats about to burst. Drm just worsens them further because now I can't mod or enjoy fixing them. Electric cars are just infuriating because they are just a battery connected to some motors. The complicated part is a fuckin computer chip why is everything sealed. All this effort for a car that looks like a car shaped cum blob.

Mentioned this in another comment, but many regions now mandate that EVs have noisemakers built in which emit sound at low speeds (<40km/h or so).

Apparently all the deer around me are fuckin deaf going by what cares I've seen hit them.

[-] creditCrazy@lemmy.world 3 points 1 year ago

I suppose different places have different animals. But in my home state at least, deer were only a problem when my folks got a f150. That ironically enough was extremely quiet. It was easily my familys most quite vehicle we had. And it was the only vehicle that had deer jumping in front of it and even hit a bear.
