The weather is not melting cars. But there was a big fire in Tucson and the heat from the fire melted plastic parts on a bunch of cars in the parking lot. The pictures in this article fairly clearly match the cars, parking lot, and background building in the picture you attached. So, are cars in Arizona melting in the heat? A few that were unfortunately ...

I focused on the US for this answer. An apology does not automatically lead to the party being found guilty: The apology may not be admissible in court (but the laws are complicated, as usual). When it is admissible, the judge or jury will be deciding if anyone is guilty or not. In many cases, an apology is not seen as strong enough evidence on its own. A ...

It's a PR stunt, and a very bad one at that. There are several debunkings out there, e.g. from ElecTrek, or (the best IMHO) from DÆrik @ YouTube. Strongest points made by DÆrik: The press release by PromoBot claims that the driver has "put the car in self-driving mode". Such a mode does not exist in available Tesla models. The Tesla "autopilot" would not ...

This is something of an urban myth - the drying time gains were made by using oven-dried enamel coatings on the parts that could withstand the required curing temperatures. The so-called "baked enamel" coating used by Ford was called "Japan Black" (produced for Ford by APV Engineered Coatings) - this is an asphalt-based enamel coating which is applied to ...

Ford has said that the F150 pickup has 150 million lines of code. According to the New York Times: Twenty years ago, cars had, on average, one million lines of code. The General Motors 2010 Chevrolet Volt had about 10 million lines of code — more than an F-35 fighter jet. Today, an average car has more than 100 million lines of code. So, even if ...

...but China only has 37% of the world's reserves Michael Karnerfors has provided evidence that China produces 95% of the world's rare earth elements. However, China does not hold that much of the world's reserves of such metals. The US Geological Survey mineral commodity summary for 2017 for rare earths gives China's 2016 rare earth's production at 105,...

The car does not run on water. The article you link says quite clearly that "The car runs on acetylene gas". Acetylene is an explosive gas that is used for welding, and before the invention of electric lamps it was used for lighting. It is produced from the reaction of calcium carbide and water, as follows: CaC2 + 2H2O → Ca(OH)2 + C2H2 The problem is ...

This calculation is pretty much worst-case for the bicycle. It doesn't take into account that food production has actually stored CO2 from the atmosphere which is now just released back, while fuel was originally underground and its CO2 is added to the carbon cycle. Neither does it take into account mercury/other emissions, nor the wear-and-tear in cars and ...

In the EU, speedometers are not allowed to display a speed that is lower than the speed the vehicle is traveling. Manufacturers calibrate speedometers to comply with this regulation as they would not be allowed to sell their cars if they did not. Reference - EU Regulations for Speedometers (75/443/EEC) The speed indicated must never be less than the true ...

Mythbusters visited this topic in both episode 22 and episode 38: Episide 22 PARTLY CONFIRMED * Tests were performed under varying conditions (55 mph versus 45 mph). The 55 mph test used a computer to estimate fuel efficiency based on air intake, not actual fuel consumption, and showed A/C was more efficient. The 45 mph test consisted of running the ...

It looks like modern cars really are better when you adjust for survival bias My subjective impression is that modern cars are much more reliable than older cars. But I can see one reason why fans of classic cars might disagree with this impression and it is one of those factors that can seriously bias someone's' perception. It is simply that any old car ...

LOC is a particularly bad metric, because it raises the question of what is a line of code. Do you include whitespace and comments? Compiler directives? Preprocessor definitions? How about lines containing only braces? Do you include makefiles or whatever scripts do the building? And in the end, does the number of LOC truly relate to the complexity of ...

Alright, this is actually a tough one as it seems to be fairly universally agreed (e.g. insurance companies, safety commissions, state governments, etc.) that cruise control should not be used in the rain or in icy conditions. The ICBC summarizes what most of the arguments against using it are: Turn off the cruise control: Wet roads can cause wheels to ...

A search on https://tineye.com led me to this tweet by @AyeElleJay with the caption "Slimmmmm! Arizona weather real different 😩" against that image. Replies to the tweet questioned its validity, and a user named @TheMutHouse replied "this is from a recent fire in tucson, the neighboring apartment buildings cars were melted." I'm not sure if it's the ...

No. According to a 2005 report from National Highway Traffic Safety Administration (NHTSA): The number of billions of miles driven and the number of fatalities on US roads increased slowly [data from Table 1 and Table 2]: 2000: 41,945 fatalities over 2,747 billion miles. 2001: 42,196 fatalities over 2,797 billion miles. 2002: 43,005 fatalities over 2,856 ...

While it's obvious, as @Adam Davis points out, that complex products, like cars, are not manufactured in a single day, it may still be of interest when critical parts of the car, such as safety belts, were installed, if Mondays and Fridays are bad days for manufacturing. Statistics for manufacturing quality per weekday are hard to come by. However, if low ...

The short answer is that no, electric cars are most definitely not at a thermodynamic disadvantage compared to a combustion engine. Quite the reverse, they have the advantage. Electric cars are about 4x as efficient as fossil-fuelled combustion engines, tank-to-wheel: ICE engine efficiency is around 20%. Electric engines tend to be around 80-90%. And the ...

Answer: Seemingly yes. Bonus: Probably simpler than most people think. First off, this is a great question. I've heard many people claim this is true, though not having a remote keyless system, haven't had a chance to do it myself. Looking it up online, there's virtually no "official" information about why this works. I'm going to list the most credible ...

Yes, older cars used mechanical odometers, which go forward or backwards, depending on which way the gears are turned. Modern cars use electronic odometers. I couldn't find anything indicating over what time period this changed. It was well before my time behind the wheel, though. I also found a January 1961 article from Popular Science Magazine on the ...

And the mechanical friction caused by the alternator does not depend on whether electricity is being needed or not. Correct. In other words, when energy is not needed it is wasted Wrong. The electrical energy produced by the alternator is not the result of mechanical friction but of magnetic force on top of the (very small amount of) friction, which ...

Is formaldehyde the sole source of the 'new car smell'? No. It's more than likely the combined smell of the VOC's (of which formaldehyde is one) emitting from the interior, as there's over a dozen VOC's which are present. Brown, Stephen K and Min Cheng, 2007. Volatile Organic Compounds (VOCs) in New Car Interiors They found that the amount of VOCs ...

I did some more research on this tonight, and was able to answer my own question, at least to some extent. The conclusions seem to be: For the world as a whole, this is a very unlikely claim. For the United States of America in particular, this likely true, at least for the deaths of Americans in wars since the country was founded. This is possibly the ...

At least in Canada, no. Canada actually has an "Apology Act" that essentially says that you can apologize for something and that apology is not to be considered a confession, admission of fault/guilt.

No Once upon a time on old car engines this was required, and piston engined aircraft warm up because they stress their engines to the maximum as the first thing they do. But this is no longer necessary for modern cars. The recommended warmup time vary between 15 seconds and three minutes. Canadian Department of Natural Resources: Contrary to popular ...

I doubt you will find a definitive answer to this question, as Ohio did not even require vehicles to be registered until 1905, so there would be no way to know definitively how many operating motor vehicles there were in 1895. However, if anything, I would suspect that there were no operating motor vehicles in Ohio in 1895. Wikipedia cites a study by L. ...

Mathematically accurate From Cornell University News: An acre of U.S. corn yields about 7,110 pounds of corn for processing into 328 gallons of ethanol. That's 3,225 kg and 1241 liters. Let's assume that the "large SUV" has a twenty gallon (76 litre) tank. So that's 7110 pounds divided by about 16. That comes out to 433 pounds (196 kg) of corn. ...

Safety rules According to a December 2013 article in USA Today, the XL1 cannot meet US safety rules. The latest teaser: XL1. It's a spaceship-like, ultra-high-mpg, plug-in diesel-electric hybrid. VW used exotic, but obtainable, materials and technologies to craft a mileage-above-all car able to get 261 mpg in European tests, equating, very roughly, to ...
