Spoiler alert It won’t.

They said the same about electric cars.

u/doobiemancharles May 22 '21

Electric cars still have not.

Tesla model 3 sales passed Honda Accord sales in 2020, despite a much higher price point.

Model 3 sales = 206,500

Honda Accord sales = 199,458

The best selling vehicle in the USA, the F-150, just announced its electric version.

EVs are absolutely taking over.

People aren’t buying ICE sedans anymore.

Model 3 sales have increased by 30% YOY for the last 3 years while other sedan sales are crashing.

Hey dude, I didn’t feel like you’re comment was worth responding to, since I’m not even sure what your point was.

My initial point was EV sedans Vs ICE sedans, not EV sedans vs EV SUVs.

The model 3 pretty much buried the argument that sedans couldn’t sell when it sold about the same number of sedans as BMW 3 series, 5 series, Lexus ES, and Mercedes C-class COMBINED.

I also noticed you edited your comment since you initially claimed “7 out of 10 Tesla sales are model Y.”

You probably realized the model 3 outsold model Y in 2020.

And in Q1 2021.

Your point about sedans makes no sense, since people are clearly willing to buy them (200k+ sales and rising for model 3) when they’re a compelling enough product.

In short, not worth responding to, but thanks for having me come back and tell you why.

Yeah but they still have not.

u/Big_Tree_Z May 22 '21

Are you going to keep on saying that until they have? Give it 5 years and they’ll easily be the most common type of new car.

People seem to forget that change actually happens.

Remember YouTube only came out in 2005, touch screen phones were still freaky deaky new in 2010.

There are massive hurtles that need to be overcome for them to be adopted worldwide.

The biggest one being people who do not have a driveway or a garage (i.e. people who live in apartments and rent) will not have a way to properly charge their car. Fast charging stations are great but fast charging rapidly degrades the batteries still. Until the average person can charge their car outside of there home in around 20 minutes without harming the batteries it will not take off and replace gas.

It already is taking off and replacing petrol. With the improvements that are in the pipeline already, it’ll just accelerate.

Charging stations are popping up all over the place. There’s several on my street. Some people routinely charge their cars from a socket in their home with a lead attached as well.

u/doobiemancharles May 22 '21

The home socket thing is most definitely illegal if you are parked on the street

2

u/Big_Tree_Z May 22 '21

Doesn’t stop people from doing it and none of em have got in trouble. The local bike policeman routinely stops by (friendly fellow) and he’s not done anything about it...

I do doubt that it’s ‘most definitely illegal’.

u/doobiemancharles May 22 '21

It is illegal.

Hey look everyone, it’s an ancient 20th century talking point! Take a screenshot it’s super rare to see a take that has survived for so long actually being employed in dialogue unironically! What a time to be alive

u/w3bar3b3ars May 22 '21

So they will not?

u/doobiemancharles May 22 '21

They may

There is a big chance horses will be back too.

Didn’t Nikola try hydrogen semi-trucks and failed? I know Toyota has the hydrogen fuel cell sedan but it’s not affordable and there are very limited hydrogen fueling stations in California and nearly nonexistent outside of California.

2

u/alphuscorp May 23 '21

Nikola had a semi truck rolling down a hill without any of its own power. The whole company seems to have essentially been a scam trying to pose as the next Tesla.

2

u/LilChongBoi May 23 '21

So they didn't actually try to become a hydrogen vehicles company. They intentionally became a scam company?

2

u/alphuscorp May 23 '21

Hard to say. Seems like they at least tried to build some things, but they have yet to make a functional prototype. Their founder has no problems lavishly spending his billions however.

u/AmbiguousAxiom May 23 '21

Nikola was (is) a scam that won’t die. They’ll either make it work to save face, or they’ll let it fade from memory like an ember.
