Stopped coming to Jalopnik because of politics. Then I heard they were going to purge the political crap from Jalopnik after Gawker media went bankrupt. Then I came back and this crap is still on here. What does this have to do with automotive journalism? Was it because there was a sprinter?

Saying its energy is low per volume seems misleading. No shit, its a gas. If we look at energy / weight on the other hand...
-Gas - 46.4 MJ/kg
-Lithium Ion - 0.875MJ/kg
-Hydrogen - 119.93MJ/kg
Infrastructure will come with demand. Very weak arguments for not using hydrogen. Want a stronger argument? Its not hard to…

The physics is different in the example you gave vs the example above. The deer was probably stationary or perpendicular and not going the same direction of you. The Mercedes was more than likely only going slightly faster than the semi upon impact.
To be fair, that isn’t in the Jalopnik article. In fact, the Jalopnik article paints a very different story.
The short circuit is a hardware failure, but the software is unable to identify the error and the car accelerates. Since hardware is expensive to replace, I’m betting they’re programming the software to identify the error and allow cruise control to be disabled rather than creating the run-away condition.
Second year? I thought that was first year physics.
If you will note my post was at 12:28pm and that update was at 4:04pm. Thanks for playing. You can look up my other comments if you want to learn more on my argument.
You posted an article that pretty much confirms what I said. They stated that a Camry was unable to come to stop before the brakes faded at 120mph. Look up how energy works and how the heavier X5 would have done in the same test then come back to me with your so called data. The article also isn’t scientific. It…
If anything that enforces my point. That article states that the Toyota, which I assume is in tip-top shape, was unable to come to a complete stop. This BMW is heavier and going about the same speed. Energy is 0.5(mass)(velocity)^2. The brakes would boil over before coming to a stop. Also brake fluid is water hungry.…
I have a 2002 330ci that does NOT override the brakes. I figured the x5 isn’t a v8 and would have the same engine. That statement was a added after I posted.
The update hadn’t been added when I posted my comment. My 2002 BMW 330Ci doesn’t override the accelerator. Assuming the X5 isn’t the v8 it should be the same engine.
That’s interesting. BMW says that it has brake override, but my 02 BMW 330Ci does not. Possible that the auto and manual have different software. Also my 02 Jetta does have brake override.
The vehicles brakes are not enough to overcome the accelerator. BMWs, at least ones from that generation, do not electronically override the accelerator either. In fact this is a dumb idea to keep spreading. If the vehicle’s brakes don’t overcome the accelerator all you’re going to do is boil over the brake fluid and…
Computer security requires a little more than that. Requiring a specific string be sent to the phone for the phone to respond with the GPS location is, to me, security through obscurity. Meaning that the only reason it is secure is because something is unknown. A true secure system is a system that is secure even if…
Security Concerns wouldn’t allow that. Anyone who got the phone number would know the location of the car. If you personally want a GPS to send locations via SMS, that’s fine, but it isn’t a business model.
I guess you can throw a cheap smartphone into your car with this and use an app like “Find my iPhone” to locate you’re car on the cheap. Even most older iPhones are only $100 which is within the price range the OP was looking for. I can’t think of a way for this to be profitable for a company to do though. In order…
If that is the case, I suppose it could be possible to use a “call-only” cell service. I think you can get these pre-paid for about $1 a month. With this, you could “call” your car and have it feed you data like dial-up. I don’t believe this would be saleable for market though. Not only does security become an issue,…
We do have this. OnStar for example. The difference between what you’re saying about your friends and your car is your car doesn’t pay a monthly phone subscription. I think most people wouldn’t pay an extra $40 a month just so their car can have a “cell phone.”
