    Sounds like my mother, though my mother doesn't have a backup camera and won't use a mirror

    EVs are theoretically more fun to drive because lack of throttle lag. However this is not the case IRL.

    1. EVs are overpriced.
    Already mentioned before, given the complexility of the powertrain, EVs are much cheaper to produce, but most if not all of them, have higher price than their ICEV counterparts. An EV is a positional good, lots of people buy them to show their "green, futuristic, innovative" social status, which results in Evs greatly exceeding the value of "conventional" vehicles.

    2. EVs have shorter life expectancy.
    An ICEV can still drive even after 10 or even 20 years, its life are extended by proper maintenance. An EV cannot be maintained and its life is more or less fixed.

    3. Most EVs have lower reliability than their ICEV counterpart.
    NOT because of electric drivetrain. Electric drivetrains are way simpler than an ICE drivetrain so EVs are more reliable theoretically. However, most if not all EVs are highly computerized. The more computerized the vehicle, the lower the reliability of the vehicle. Since EVs are more computerized compared to its ICEV counterparts. Most EVs IRL are less reliable.

    An EV without any "smart" feature and assists are ABS/ESC at most would be the most fun to drive, but really hard to find IRL.

    Note: I'm actually an EV enthusiast. However I do point out the disadvantages and flaws of EVs, often mercilessly, which might make some people to believe that I hate EV.

    To be fair it's only the battery life that is fixed, the car itself should theoretically last a long time, if it weren't for all of the extra computers.

    Hell in theory even the computers shouldn't be a problem. Computers really shouldn't just simply go wrong, look at things like the power grid and trains which are often controlled by computers from the 80s without refit.

    No maintenance? The chemistry in the Tesla is good for 5000 100-0-100 charges (it is not plain lithium ion, it's closer to lithium iron phosphate). Already proven you get 10 to 100 times gains by only doing 80-20-80. It's also steady proven that plenty of Tesla's have done 100000 plus miles with almost no measurable degredation. But more so, the battery is replaceable. The transmission fluid, shouldn't need touching, but just in case, it's replaceable. Motor assembly is an easily removable module, does contain the inverter too but that is again easily removable from within the motor assembly.even the computers on a Tesla have been hacked and modified before, the motors have been made to work with something as simple as an Arduino. That a Tesla isn't moddable or maintainable is about as absurd a claim as me saying the sky is falling. The skills needed are just different.

    Hell even the dumb eMMC write limitation in the model S killing the infotainment and by extension the car, I have resources to repair myself.

    Well, this is outright misinformation. Tesla batteries are nothing close to lithium iron phosphate. Li-ion batteries have different chemistries, LiCoO2 LiMn2O4 LiNiCoAlO2 and LiFePO4 are most common. Tesla(and some other vehicles) are using LiNiCoAlO2 chemistry, the voltage is the same as LiCoO2, 4.2V@100% 3.7V@50% 3.0V@0%, where a lithium iron phosphate (LiFePO4) battery spend 90% capacity in 3.3V-3.2V range, 3.6V@100%. 3.7V batteries suffer from both cycle and storage time. The typical cycle life is 300~1000 to 80% rated capacity, not even close to 5000, and storaged at higher SoC (60% or more) will result in a shorter calender life. LiFePO4 chemistry, on the other hand, has lower energy density and lower voltage 3.2V, has much longer life expectancy, cycle life 2000~7000. And LiFePO4 can storage at 100% SoC a long time without affecting calendar life.

    Bentley S2 6.25 litre V8 classic car, with my grandad we took it for a drive through central london, she held together (just)... no vapour lock issues, no overheat..

    until my grandad stopped to go to the toilet... nope didn't want to go after that. so we open the bonnet a touch, wait 15min for it to cool down, and it fires up not too bad.. lots of engine knocks and pinking, and we make our way home..

    So on this 50mph road, there are two lanes, dual carriageway, lots of traffic light, every green light is a dragrace it seems, now this 1959 bentley is in the overtaking lane, to the left of us is a toyota yaris, 1L and you can hear this poor thing rev right up to get going, we lose ground on the yaris at first as the bentley is a bit slow off the mark, but once the transmission has come out of 1st and into 2nd, boy does this thing make up ground! goes barreling forwards passing lots of cars and wafts on gathering speed... until the next light when it happens again :p Engine pinking at the start, revs pick up, engine picks up, 2nd gear and the car stammers a little bit.. pink pink and then whooosh... off it goes!
    Quite a lot of fun! Can't wait for one day in the future when i can drive a classic car like that.. :p
    I think we will keep that car until either it gets written off in a bad crash, or the world runs out of petrol..

    But anyway, lots of vapour lock issues with that car, part of the personality of it i guess

    Electric cars are the future though, and for good reason. Of course, ICE performance cars will still exist, money talks and performance cars are too big of a market to ignore.

    No no no, I have seen the future. And it is bright.

    Honestly though, how cool would it be to walk into a dealership and say "I'll take the performance spec nuclear reactor please"

    that would be cool. Car accidents would probably cause Chernobyl II, though...

    And also it's proverbial hell to get those materials IIRC.
    also, yall just gonna forget hydrogen ICE engines as an idea for the future or what?
    Think about it, it appeals to people like Chotgun Shuck and Default0.0falseflag who complain about EV vehicles not having "driving feel" and yell about how they explode, because it's literally the same as a normal ICE.
    And environmentalists like them too, the oxidization of liquid (or gaseous) hydrogen makes water and practically nothing else.
    WATER.

    Given the complications of building these cars and engineering infrastructure, I think we will have to forget them.

    "Complications"
    Lemme list those.
    -Efficient way of harnessing Hydrogen (Cough toyota hey cough that shit up we tryna save the planet here)
    -uhhhhhh
    -re-design fuel system (Literally would take maybe 5 grand and a couple days, pennies for a big auto company)
    -then idk get oil companies to get they head out of their ass and switch an oil rig to a hydrogen rig?

    Fuel tanks being ultra explosive and having low capacity?

    Hydrogen is hard to transport and store and far more flammable/explosive than batteries or gasoline

    Here’s the thing: Electric and hydrogen power are still in their infancy. Think about how long it took for the ICE to get to where it is now: the development of starter motors, fuel injection, overhead cams, etc., the development of infrastructure, like gas stations and service shops, and bringing down the cost of acquiring fuel. All that took about a hundred years. Modern EV technology began in the early-to-mid-90s, which was about 25-30 years ago. Hydrogen power first started appearing (and fuel companies “pledged” to implement it) in the early-to-mid-00’s, which was about 15-20 years ago. It’s going to take a long time for either of them to get to the level of refinement, convenience, and practicality that ICEs are on.

    Battery technology still needs improvement, computer systems need to be more advanced and more reliable, a cheap and efficient way of generating and storing hydrogen fuel cells needs to be invented, etc. All that will take a long time. Meanwhile, we’ll have people like Shotgun Chuck complaining about how they’re objectively worse than ICEs and everyone should buy a gas car instead. The problem, then, if buyers listen to people like him, is that manufacturers (the biggest of which don’t even want to make EVs anyway) will see a drop in demand for electric vehicles and stop putting any effort in improving them. Same goes for hydrogen: if people show a lack of interest, no one will come up with a way for them to be viable.

    Actually not that bad as some said because hydrogen vanishes quite quickly so unless there is a immidiate spark it wont explode. A battery or ice car can catch fire just as quickly as a hydrogen one.
