You can't just look at the number of stations. It takes roughly 5 min to fill a hydrogen tank. So while 12 EVs sit at each of their stations for an hour, you can have 12 hydrogen cars filled up in that same amount of time.
I'm actually surprised that there aren't more manufacturers interested in hydrogen. Alex on Autos in one of his videos made the case that the energy density of fuel cell far exceeds that of a lithium ion battery. I couldn't find the video, but this blog captures a lot of his points and perhaps more.

Lithium-Ion batteries cost about $2000/kWhr, and give an effective 500 charge/discharge cycles; their physical life can be extended by not fully charging them, but it’s the same 500 cycles. The effective cost of the battery is thus $4/kWhr (The battery university site calculates $24/kWhr, but that seems overly pessimistic). Combined with the cost of electricity, and the losses in charging, the net cost of Li-Ion battery power is about $4.18/kWhr, several times the price of gasoline, even including the low efficiency of gasoline engines.
See below for much more realistic comparison between the two techs and you'll understand why hydrogen isn't going to takeover

You might as well find a video showing how few CNG stations there are compared to EV charging stations.

Hey @#1 STUNNA do you think the new yoke steering is a cost cutting measure by Tesla to save a few bucks on the upper half of the wheel?

LOL no. They think it looks cool, and doesn't block the cockpit display. Like the iPhone FaceID notch reports are coming in that people that initially didn't like it have adjusted to it after a few hundred miles and now don't mind it. Over time we'll see if that's the general consensus or is it still hated like the MacBook Pro touchbar 5 years later and they finally remove it ¯\_(ツ)_/¯

MT is not too happy with it.

however, we were left underwhelmed by its execution after a week of living with a so-equipped Model S Plaid. This was especially true when driving at lower speeds where the car's quick, but not quick enough, 14.0:1 steering ratio made it difficult to complete near-full-lock turns without awkwardly fumbling for the device's (purposely) missing upper rim out of habit.

Will see what features EA / others could do to redeem themselves. May be raise their prices. . But competition is coming. .

Just curious, why can't legacy auto do this?

So you posted information provided by Tesla propaganda sources as they are some kind of fact, such as "only tesla can implement features like this legacy auto couldn’t do it if they tried"
That is like the lawsuits Trumpettes filed and quoted articles from NewsOne as evidence.

I dont think other cars would wanna be tracked like that anyway.....
Obviously there are not enough charging stations, that is the only reason to even have something like that.
I have yet heard the need to track how long the wait at a Gas station is. cuz there isn't any.

Nope. i dont understand the logic behind it. Having to wait under the sun for 15 mins with AC on just to save $3 on a tank, when you can just go to the gas station around the corner and be in and out in 5 mins.
But that wait is a voluntary wait to save $$. Not the same as waiting for chargers because they are full.

They don't have to track the cars, they just need a link in with the charging company that says how many of the chargers are in use and how long they've been charging. That's literally it. It's not like Tesla's system gives a down to the minute indication of wait time, it just says no, low, medium, high. Google already does this with map locations so it's not impossible.
And how many charging companies is each auto company going to link with? We all know how great 3rd party APIs work in terms of security.

There aren't very many charging companies, this isn't hard. If Google can tell me in an instant whether or not a wide variety of restaurants are busy or not, it shouldn't be hard at all to figure this out.

Does the charger not know that there's a car plugged in and what the state of charge is for that car? Also, it's not an API, it's literally just an internet connection to a web page. The car doesn't need to send any info out, just has to receive it from a web page.

And each one likely don’t want to give away their monopoly to others for whatever reason.
Maybe someone like google / Apple should offer them a solution which everyone might accept (such as create an icon in Apple CarPlay/ android auto) that offers everything they need.
Right now these softwares are playing “you are the problem, not me” as evidenced in the video showing a Mach E struggling with an EA charger. You know what I mean.

No, they don't need a single platform. They all just need to serve the data for the cars to pull information from which, to be honest, is not at all difficult to do. This is not impossible and it's certainly not something only Tesla can do. Again, someone with even a small modicum of technical knowledge can tell you this stuff. Stop believing BS twitter posts, it's basically the same as getting your news from OAN or Newsmax.

And it’s been a horrible experience for VW owners. Watch basically any road-trip video out of spec motors does with the Taycan, Id.4, or mach3

So why aren't they doing it? May be they don't it is important enough to divert their resources into.
In theory Tesla could go further and anticipate a future rush hour at charge station by analyzing what every car's probable destination and charge state is, but that would be too much invasion of privacy.

All the hatters in here saying that the Tesla supercharger network is vastly superior to anything else and that’s why they’re buying a Tesla but then in their next breath saying that electrify America could totally do what Tesla does. Then if that’s true why are you buying a Tesla

Andrei Karpathy, head of Tesla autonomy division, did an FSD Zoom presentation and went into detail about why they removed radar. The video was in YouTube and was privated so I haven’t found a full source yet, but this video has some good clips with great new info explaining why radar sucks compared to good vision
