What driving data is Android Auto collecting from us?

In-car solutions like Apple CarPlay and Android Auto make using your smartphone while driving increasingly easy, by replicating most of the gadget's functions on a vehicle's infotainment screen. In fact, they rank among the favorite automotive features available today by Autoblog editors. While there's certainly added convenience, Motor Trend claims Google is collecting a huge array of data during trips, as well. Although, that might not actually be the case. In a rundown of the upgrades for the newly refreshed Porsche 911, Motor Trend asserts that the iconic coupe doesn't have Android Auto because of alleged privacy concerns. Reportedly, Porsche elected to only include CarPlay because the Google tech collected info on a vehicle's speed and other data. The German company didn't want to share all of that vital info with another corporation. Google opposes the allegations, though. "We take privacy very seriously and do not collect the data the Motor Trend article claims such as throttle position, oil temp and coolant temp," the company said in a portion of a statement to TechCrunch. Android Auto does use a vehicle's GPS system for location info, and checks whether it's in Park or Drive to enable some features. Also, users must opt-in to sharing the first time that they connect their phone. There might be an explanation for this confusion, according to TechCrunch. Allegedly before Android Auto launched, Google did want more vehicle data, but the company eventually changed course. Porsche may have based its decision on this earlier version. This case just shines a light on the growing question of automotive privacy and Google's potential role. The government has been unhappy with how automakers have handled this responsibility, so far, though.

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.

Automakers not currently promoting EVs are probably doomed

Okay, let's be honest. The sky isn't falling – gas prices are. In fact, some experts say that prices at the pump will remain depressed for the next decade. Consumers have flocked to SUVs and CUVs, reversing the upward trend in US fuel economy seen over the last several years. A sudden push into electric vehicles seems ridiculous when gas guzzlers are selling so well. Make hay while the sun shines, right? A quick glance at some facts and figures provides evidence that the automakers currently doubling down on internal combustion probably have some rocky years ahead of them. Fiat Chrysler Automobiles is a prime example of a volume manufacturer devoted to incremental gains for existing powertrains. Though FCA will kill off some of its more fuel-efficient models, part of its business plan involves replacing four- and five-speed transmissions with eight- and nine-speed units, yielding a fuel efficiency boost in the vicinity of ten percent over the next few years. Recent developments by battery startups have led some to suggest that efficiency and capacity could increase by over 100 percent in the same time. Research and development budgets paint a grim picture for old guard companies like Fiat Chrysler: In 2014, FCA spent about $1,026 per car sold on R&D, compared with about $24,783 per car sold for Tesla. To be fair, FCA can't be expected to match Tesla's efforts when its entry-level cars list for little more than half that much. But even more so than R&D, the area in which newcomers like Tesla have the industry licked is infrastructure. We often forget that our vehicles are mostly useless metal boxes without access to the network of fueling stations that keep them rolling. While EVs can always be plugged in at home, their proliferation depends on a similar network of charging stations that can allow for prolonged travel. Tesla already has 597 of its 480-volt Superchargers installed worldwide, and that figure will continue to rise. Porsche has also proposed a new 800-volt "Turbo Charging Station" to support the production version of its Mission E concept, and perhaps other VW Auto Group vehicles. As EVs grow in popularity, investment in these proprietary networks will pay off — who would buy a Chevy if the gas stations served only Ford owners? If anyone missed the importance of infrastructure, it's Toyota.
