60 Minutes Dubbed Engines Noise Over Tesla Model S 544

Now, with ENG style recording, the microphones are typically pointed directly at the reporter, which also has the unfortunate effect of picking up everything behind the subject, too.

A friend of mine just bought a Tesla. As far as I know it maybe the only one in the St. Louis area. I recently bought a Chevy Volt. We were at an event and the topic came up. One of the people there asked me why I went with the volt. And the answer was fairly simple:
My wife's commute is 15 miles round trip a day. Maybe 20 if she does some afterwork shopping. So the vast majority of the time it's running on electric. But my Dad lives ~ 70 mile round trip from us. He's older and I'm usually out there once a week to check up on him or help him clean out gutters or whatever needs to be done around his house. I have farms that are 300 mile round trip that need seen after. That is certainly a problem with a Tesla.
Also my budget for a new car was between $25,000 - $30,000. With lower base price for 2014, tax credits, and GM card earnings the Volt fit in the price range and was a little bit smaller of a car than the Malibu Eco, which meant it fit in the garage better.

Frankly, my dear, nobody gives a damn about what a particular car sounds like in a particular situation except for us nerds. Unless the media piece is explicitly focused on how something sounds, having realistic audio is actually distracting to the audience. There are thousands of little noises that our brains filter out because we don't care about them. Someone walks down an alley in a city at night, and their ears will pick up rustling clothes, a jingling zipper pull, creaking pipes, whistling wind, noisy cars, buzzing fans, someone shouting a block away, et cetera. Of course they'll hear their own footsteps, but that's the only thing they'll notice. A good audio engineer will strip out the soundtrack completely, add a noise floor to match the rest of the production, and dub in footsteps. Leaving in the raw audio will also leave in those background noises, but because the audience hasn't been exposed to them, the background noises stand out more, distracting the viewer from the film's actual subject.
Having tires squeal on gravel is similar. Rather than background noise, the distracting element is that the sound just isn't what's expected. In an action shot, there usually isn't time to properly establish the scenery.
Consider a scene where the Dukes are waiting by the side of the road, and leave in a hurry. They hop in their car, step on the gas, and rush off from a standstill. Sure, visually you can see it's a soft shoulder, but audibly, your brain hasn't bothered to think about dirt or gravel noises. The first sound most audiences associate with a fast departure like that is a squealing tire. That's what they expect, so having the more realistic grinding noise will raise a different cue in the audience's mind. They'll wonder briefly why the engine is grinding, and worry whether something bad happened to the General Lee.
In another scene, the boys have pulled head-in to a parking space. After the iconic hood-slide, they have to back out on the gravel before they can take off. That's a chance for the audio engineer to put in a slow gravel noise, hinting to the audience that they should expect to hear gravel. By the time the car accelerates, the audio scene has been established in the listeners' minds. A fast gravel grind may be acceptable, but the squeal is still less likely to distract.
The professional audio technique, and similar techniques on the visual medium, are a major reason behind the perceived quality difference between professional films and home movies. Subtle echoes, timing, and the selection of noises all contribute to keeping the audience focused in the direction the director wants. Blame him if something bothers you.

Electric cars and downshifting (Score:5, Interesting)
Actually there are valid reasons for an electric vehicle to shift gears - just because many electric vehicles only have one gear doesn't mean there aren't valid reasons for having multiple gear ratios.
Although in the case of EVs, shifting tends to be more speed-dependent than load-dependent. While EV motors are typically constant-power, there ARE torque limits at low speeds due to current limits. Although this usually means that an EV that has more than one gear ratio needs far fewer than an internal combustion vehicle. (as in, even two gear ratios is usually enough in the rare cases where only one gear ratio wasn't.)
See Charles Guan's burnoutchibi project as one example.

some hybrids pump engine noise through speakers to appease the driver
They do that for safety too, not just to appease the driver. Domino's Pizza in the Netherlands made a marketing coup with this a few years ago when they switched to electric delivery scooters. They added audio of a guy going "VROOoooooommmmmm! Lecker-lecker-lecker... Vrrrooooommmm!" [youtube.com] (Apparently, "lecker" means "yummy" in Dutch.)
