VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.

UK workers strand car on island of asphalt to keep working

Generally speaking, when you illegally park your car, you're likely to get ticketed and towed, but there is probably at least one motorist in Scotland who wishes that was the case. After workers had blocked off a portion of the parking lot for the Edinburgh Waverley railway station, the driver of this Mercedes-Benz S-Class reportedly moved some of the barriers to park in one of the empty spots.
Rather than having the vehicle towed, the work crew simply tore up the asphalt around the leaving just the one parking spot intact, and as you can see in the image above (posted to the Twitter account of Harold Norstad), the crew even built a small asphalt ramp so the car could get off its blacktop pedestal. Since this happened last week, there's no word as to whether the car was eventually moved or towed for the resurfacing work to continue.
Let this be a warning...
