The iPhoneX has the strongest glass. … but actually breaks easier than the iPhone 8 glass.

Are you sure? I saw a YouTube drop test video and the iPhone X survived multiple drops from head height (~66") onto concrete without breaking, but the iPhone 8 shattered. https://www.youtube.com/watch?v=8vHCBwJVeO4 I've dropped my case-less iPhone X 5 feet onto bathroom tile and not even a noticeable scratch afterwards.

Not at all scientifically done.

"Well, it's a fraction of the cost to operate, but if a tire blows, the mechanic will have to detach a piece of plastic. So I think we'll pass."

It's way beyond that. 1. it makes changing a tire more complicated, and time is money, the longer it takes to change a blown tire the higher the penalties 2. when a semi tire goes, it goes hard , as GP noted with this arrangement the cowling will probably shatter, requiring a replacement (not just a replacement tire) and the pieces taking out other tire. If the cowling does not break, it will funnel bits of tire stra…

When a rear tire blew on my campervan, in addition to having to replace the tire, the blowout caused many thousands of Euros worth of damage to the bodywork.

Is a center seating position common for truck drivers? It looks amazing , but it is different enough from my normal consumer driving experience as to make the entire product a non-starter if it were in a consumer car. I've developed decades of training and muscle memory sitting on the left side of the car. I wonder if there will be a measurable impact on accident rates.

Have you considered what portion of said training and muscle memory was directly attributable to compensating for cabin asymmetry?

EU will like these huge windshields, because of the pedestrian safety.

"Contrary to passenger cars, there are currently no direct vision requirements for trucks. Direct vision – what you can see with your own eyes – has a number of benefits compared to indirect vision (mirrors and camera’s). To measure direct vision the Commission should use a standardised methodology."

Very nice summary on truck blindspots : https://www.transportenvironment.org/sites/te/files/publicat...

What's the axle pressure compared to traditional semis?

Semis are going to be less and less popular in the EU when more countries add fees for distance driven which is proportional to wear, which is twice for a semi compared to a non-semi.

Ok as a mechanic a few million questions: * What happens when a wheel seal goes? Do I have to remove all that ridiculous plastic on #2,3 axels?? * What happens when a tire blows? Is it going to destroy all that plastic and take out a few more tires in the process? * Why all the glass? I've spend entire days replacing windshields for a 12 or so truck shop which generally come in two (drivers and passengers), the Tesla…

This alleged photo shows no cover over the wheels. You can probably just not use it if you don't like it.

Why do you say it is a fraction of the cost to operate? Because the advert says so? I'll wait for concerns like the parent's to be weighed in before reaching any conclusion.

lets not compare iphonex to Elon Musk's glass. I know nothing about glass, but, I trust the guy with a company called spaceX on his portfolio to make my glass right.

It's this kind of ridiculous bootlicking that makes me dislike the Musk cult with a passion.

You should probably watch the actual reveal, it's already on YouTube. The glass was already addressed and he gave it a specific focus. Even claiming it can withstand an atomic blast.

I think that's because you have multiple factors with thin smartphone glass. The harder it gets, the more brittle it becomes. You probably won't be able to cut into it even with a pretty sharp knife, but if you were to drop it at the right angle it'd shard into a billion tiny pieces.

I have no idea how automotive glass differs, but I imagine the difference in weight and thickness requirements does impact things a lot.

This reminds me of the unfolding problem of sun roof explosions.

He states that they have spent a lot of time talking to truckers and truck companies. I would guess they believe that with an electric drive train repairs and maintenance will be an order of magnitude lower (not sure how that works for tires and wheels). Body damage should also be much lower with automatic breaking and other features of enhanced autopilot. As Musk said, broken glass is a big cost for trucking as you…

> "nuclear blast" proof That seems like a meaningless claim without size and distance from the blast.

Doesn't really matter, it is just marketing. I guess somewhere through the design phase they did some calculations on how much force it can take and checked it against silly things for Musk to say.

The only point is that it's stronger than normal glass, which is backed up with the video comparing the two different types of glass in a more realistic scenario.
