Sebastien Vettel testing Infiniti's production Etherea?

It sounds like Sebastian Vettel has had his hands full recently, juggling his Formula One racing career while moonlighting as the newly appointed director of performance at Infiniti. On that latter note, Autocar is reporting that Vettel has been testing a production version of the Etherea Concept at France's Circuit Paul Ricard.
There is still no word as to when we could see this car go into production or what it will be called (possibly the Q30), but it will likely share a platform with the Mercedes-Benz A-Class as a part of the Daimler/Renault-Nissan collaboration. The article also said that this future entry-level Infiniti would be produced at Nissan's Sunderland, UK plant.

Watch this mobility scooter drag race a Nissan Skyline with surprising results

Okay, so we may not be talking about a classic, all-conquering Nissan Skyline GT-R here. But the sub-Godzilla-trim Nissan Skyline GTS-T is still a car, after all. And, as a car, if someone asked you to lay a bet on it versus a mobility scooter (Hoveround, Rascal, you know the type) in a drag race, you'd probably take that action.
Unless, of course, that drag race were happening on YouTube, in which case you'd put your money away and open up your laptop. On the Internet it's best to never bet against the wild underdog.
We don't mean to spoil the following video for you, but come on. When you saw Skyline vs. Scooter in that headline, you had a pretty good idea of what was to come, didn't you. Needless to say, mobility scooters fitted with Suzuki GSX-600F engines are pretty quick. Strap in and scroll down.

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.
