Yes touch controls, but the comment I replied to mentioned touch screens (so usually the centre console), which only contains thing you don't really need to manage while driving.

Phew im good then, my car weighs 1 ton so i can just drive with one hand right?

The wording is probably similar here, but very few critical systems are not controllable from the steering wheel.

Wipers, volume, AC, cruise control are all controlled from the steering wheel of modern cars, there's really not anything you need to do from the centre console to drive safely. If it's not a critical system, you shouldn't be using it, physical buttons or not.

It differs from country to country, but where I live you can technically be fined for it. You will also fail your drivers test if you do it.

Technically the only thing you're allowed to fiddle with, while driving, is what you can operate from the steering wheel. You're not supposed to fiddle with radio, AC etc. from the center console while driving even if it's physical buttons.

I know people don't drive like this, but you're only allowed to take your hands off the steering wheel for changing gears if driving a manual, otherwise it's two hands on there at all times...technically

Which is why i put it in quotation marks. I couldn't remember the name of the reaction, so that was my go-to replacement.

It's a work phone, I don't bring it home with me unless I know I'll need to support a colleague in a different time zone. And I'm certainly not going to put any personal information or documents on it or use it for any personal use. My work has complete control of the phone remotely and can install/remove apps at will. I'm not even allowing it to connect to my WiFi when I have it home with me.

It has an older i3 quadcore @ 3ghz max with 16gb ram and 1tb nvme, can't remember the model number.

I think idle without any VMs or containers running is around 6.5W, so no it's not much lower.

Anecdotally my NUC runs 2 linux VMs and a couple of LXCs, so it's never truly idling, and pulls an average of 7.5W.

Yes but the overhead we have is nothing compared to the energy needed to make everything hydrogen powered. we would need an absolute absurd amount of overhead to generate all the hydrogen from overhead alone.

It's kind of dumb to intentionally waste 75-80% of the total electric energy initially generated to power hydrogen vehicles.

Using hydrogen to store the occasional grid overhead to be used for the grid later is a great idea, it should absolutely be done ASAP...but it's not a solution to hydrogen powered vehicles.

Hydrogen is incredibly inefficient compared to using electricity directly. You have to first use the electricity to make the hydrogen, this is very inefficient in itself. then you have to "burn" it to drive the vehicle, which wastes most of the energy just like ICE vehicle. So you need several times the initial energy generation to drive a hydrogen vehicle the same distance compared to using electricity directly.

Of course the batteries is then the issue when it comes to EVs, so they're not a magic bullet. But I wouldn't say hydrogen is the obvious better choice either since it is so wasteful with the energy.
