When public charging fails you and your EV

Think that owning and driving a plug-in vehicle in green-centric San Francisco is easy? You should probably think again. That's because a lot of other residents already have the same idea, and there aren't enough charging stations to keep up. A classic First World problem, for sure, but a problem nevertheless for at least one EV driver. A Wired reporter shares the experience test-driving a Nissan Leaf for a couple of days. The catch is that, like many of the city's residents, he's an apartment-dweller without a dedicated parking spot, meaning that he's at the mercy of publicly-accessible station availability. And that infrastructure, he writes, is "woefully inadequate" to handle the current crop of plug-in vehicle drivers in the San Francisco Bay Area The crux is that, while Nissan Leaf's navigation systems can direct a driver to the nearest stations, they neither say if the stations are occupied or if they're open to the public. The former issue is a major one because, unlike gas stations, a plug-in vehicle charging station can be occupied for hours instead of minutes. That means plug-in vehicle drivers without overnight charging access will likely constantly be on the hunt for unoccupied charging stations in the area until more stations are deployed.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

Ghosn says French ambassador told him: 'Nissan is turning against you'

BEIRUT — Former Nissan chairman Carlos Ghosn said on Tuesday that the French ambassador had warned him shortly after his arrest that his own company was plotting against him. "Frankly, I was shocked by the arrest, and the first thing I asked is make sure Nissan knows so they can send me a lawyer," Ghosn told Reuters in an interview in Beirut. "And the second day, 24 hours from this, I received a visit from the French ambassador who told me: 'Nissan is turning against you'. And this is where I realized that the whole thing was a plot." Former Nissan CEO Hiroto Saikawa, who was forced to resign last year after admitting that he had received improper compensation, told a news conference shortly after Ghosn's arrest that Ghosn had been using corporate money for personal purposes and under-reporting his income for years. The arrest of Ghosn, widely respected for rescuing the carmaker from near-bankruptcy, has put Japan's criminal justice system under international scrutiny. Among the practices now under the spotlight are keeping suspects in detention for long periods and excluding defense lawyers from interrogations, which can last eight hours a day. "When he told me that 'two hours or three hours later, after your arrest, Saikawa went in a press conference and made his infamous statement where he said, you know, 'I am horrified, but what I'm learning...'' — so when he told me he made these statements, I said 'Oh my God this is a plot'."   Related: Yamaha warns not to climb into instrument cases after Ghosn arrest   Ghosn, 65, fled Japan last month while awaiting trial on charges of under-reporting earnings, breach of trust and misappropriation of company funds, all of which he denies. The one-time titan of the car industry said the alternative to fleeing would have been to spend the rest of his life languishing in Japan without a fair trial. Ghosn said he had escaped to his childhood home of Lebanon in order to clear his name. He noted that there were conflicting stories about his astonishing escape, but declined to say how he had managed to flee. Tokyo prosecutors said his allegations of a conspiracy were false and that he had failed to justify his acts. The 14-month saga has shaken the global auto industry and jeopardized the Renault-Nissan alliance, of which Ghosn was the mastermind. Japan's Ministry of Justice has said it will try to find a way to bring Ghosn back from Lebanon, even the countries have no extradition treaty.
