White House clears way for NHTSA to mandate vehicle black boxes

At present, over 90 percent of all new vehicles sold in the United States today are equipped with event data recorders, more commonly known as black boxes. If the National Highway Traffic Safety Administration gets its way, that already high figure will swell to a full 100 percent in short order.
Such automotive black boxes have been in existence since the 1990s, and all current Ford, General Motors, Mazda and Toyota vehicles are so equipped. NHTSA has been attempting to make these data recorders mandatory for automakers, and according to The Detroit News, the White House Office of Management Budget has just finished reviewing the proposal, clearing the way. Now NHTSA is expected to draft new legislation to make the boxes a requirement.
One problem with current black boxes is that there's no set of standards for automakers to follow when creating what bits of data are recorded, and for how long or in what format it is stored. In other words, one automaker's box is probably not compatible with its competitors.

Solid-state batteries: Why Toyota's plans could be a game-changer for EVs

Word out of Japan today is that Toyota is working on launching a new solid-state battery for electric vehicles that will put it solidly in the EV game by 2022. Which leads to a simple question: What is a solid-state battery, and why does it matter? Back in February, John Goodenough observed, "Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted." And risking a bad pun on his surname, he seemed to be implying that all of those characteristics weren't currently good enough in autos using lithium-ion batteries. This comment is relevant because Goodenough, professor at the Cockrell School of Engineering at the University of Texas at Austin - it so happens, he turns 95 today - is the co-inventor of the lithium-ion battery, the type of battery that is pretty much the mainstay of current electric vehicles. And he and a research fellow at U of T were announcing they'd developed a solid-state battery, one that has improved energy density (which means a car so equipped can drive further) and can be recharged more quickly and more often (a.k.a., "long cycle life") than a lithium-ion battery. (Did you ever notice that with time your iPhone keeps less of a charge than it did back when it was shiny and new? That's because it has a limited cycle life. Which is one thing when you're talking about a phone. And something else entirely when it involves a whole car.) What's more, there is reduced mass for a solid-state battery. And there isn't the same safety concern that exists with li-ion batteries vis-a- vis conflagration (which is why at airplane boarding gates they say they'll check your carryon as long as you remove all lithium-ion batteries). Lithium-ion batteries may be far more advanced than the lead-acid batteries that are under the hood of essentially every car that wasn't built in Fremont, Calif., but as is the case with those heavy black rectangles, li-ion batteries contain a liquid. In the lithium-ion battery, the liquid, the electrolyte, moves the lithium ions from the negative to the positive side (anode to cathode) of the battery. In a solid-state design, there is no liquid sloshing around, which also means that there's no liquid that would freeze at low operating temperatures. What Toyota is using for its solid-state battery is still unknown, as is the case for the solid-state batteries that Hyundai is reportedly working on for its EVs.

IIHS: Drivers safer than passengers in frontal crash test

The Insurance Institute for Highway Safety introduced a small overlap frontal crash test in 2012 that replicates what happens when the front corner of a car impacts another object. In the test, vehicles travel at a speed of 40 mph toward a five-foot-tall barrier with 25 percent of the total width of the car striking the barrier on the driver side. One would assume that vehicles with good small overlap front ratings would protect the driver and the passenger equally. But a recent study from the IIHS proves that passengers aren't as protected as drivers. The IIHS conducted the test on seven small SUVs with good driver-side small overlap ratings and only one of the vehicles, the 2016 Hyundai Tucson, performed well enough to be given a good rating. The other SUVs performance ranged from poor to acceptable. After reviewing the results of the test, the IIHS is deliberating whether it should institute a passenger-side rating as part of its Top Safety Pick criteria. "This is an important aspect of occupant protection that needs more attention," states Becky Mueller, lead author of the study and an IIHS senior research engineer. "More than 1,600 right-front passengers died in frontal crashes in 2014." Since the small overlap front test was introduced, 13 automakers have made structural changes to 97 vehicles with roughly three-quarters earning a good rating after the adjustments. The IIHS' test for frontal ratings is completed with a dummy in the driver's seat and with a barrier overlapping the driver's side. Which makes sense, as passengers aren't always riding in a vehicle. "It's not surprising that automakers would focus their initial efforts to improve small overlap protection on the side of the vehicle that we conduct the tests on," states David Zuby, IIHS executive vice president and chief research officer. "In fact, we encouraged them to do that in the short term if it mean they could quickly make driver-side improvements to more vehicles. As time goes by, though, we would hope they ensure similar levels of protection on both sides." As the IIHS' test revealed, there's a massive difference in safety between the two front seats. Increase passenger safety, according to Mueller, would require automakers to strengthen the occupant compartment by using a different type of material or by making it thicker.
