Tesla behind lobbying push to ditch side mirrors

The National Highway Traffic Safety Administration passed a law yesterday forcing new cars in the US to come with standard backup cameras by May 2018, and if Tesla has its way, this could be just the beginning of changing how motorists see out of their vehicles. The electric car manufacturer has teamed up with the 12-member Alliance of Automobile Manufacturers lobbying group (which represents major companies like General Motors, Toyota and Volkswagen) and filed a petition on Monday asking NHTSA for permission to replace sideview mirrors with cameras.
Currently, side mirrors are required on cars in the US, and they can't legally be replaced by camera technologies filling a similar role. The petitioners' chief argument is that sideview mirrors add drag and decrease fuel economy. According to Automotive News, Tesla founder Elon Musk has been lobbying for laws that allow automakers to use sideview camera systems exclusively for the last two years, but claims it's nearly impossible for a single person to change the regulations.
Sideview cameras have been on concept cars for decades, but augmenting external visibility with cameras and sensors has been a growing trend in production automotive technology over the last five years or so. Nissan uses its Around View Monitor to supplement mirrors with a bird's eye composite view of the vehicle during tight maneuvers, and the LaneWatch system from Honda displays a rear-facing passenger-side view to eliminate blind spots during lane changes. Tesla's early Model X concept (pictured above) had small pods on the side with cameras mounted in them, but more recent versions have switched to conventional mirrors.

Silly dyno, that Tesla doesn't have 2,000 lb-ft of torque

Torque. Lots of torque, right off the line. That one benefit presented by an electric motor over its internal-combustion sibling, and the Tesla Model S delivers it in spades. 443 spades, to be precise, or about as much as a Bentley Continental GT or McLaren 12C. But when one Emmanuel Chang put his electric sedan on a dyno up (way up north) in Edmonton, Alberta, it registered a whopping 2,000 pound-feet!
Of course that number isn't correct, as no car on the road produces that much torque. Even a Bugatti Veyron produces "only" 1,000 lb-ft, give or take. Clearly something's amiss here, but the problem the dyno had in reading the Tesla's torque apparently doesn't come down to its electric powertrain. (Nor does it have anything to do with the northerly latitude or the interference of polar winds.) It comes down to the shiny, ten-spoke alloys.
Apparently this type of dyno measures torque by running horsepower and wheel revolutions through an algorithm. It measures horsepower at the wheel (which, at 436 hp, wasn't far off of Tesla's own rating of 416 hp) and uses a stationary optical sensor interfacing with a reflector on the wheel. Every time the reflector passes the sensor, it counts one revolution. But since the Model S has shiny ten-spoke wheels (and we presume because it was taken outdoors under bright sunlight), the sensor thought that each passing spoke was one revolution of the wheel... when it was, in fact, ten times too much.

Tesla open-sources all its patents

When Tesla CEO Elon Musk says that he's thinking about something, you definitely need to pay attention because it's likely something big. In an eloquently worded press release (a very rare thing indeed) Musk explains reason after reason why Tesla is opening up all of its patents, effective immediately.
According to the missive, Tesla initially applied for patents on its technology because it was afraid bigger, more powerful automakers would take its ideas and destroy the tiny automaker. However, that hasn't happened. Musk claims that while the company has grown, "electric car programs (or programs for any vehicle that doesn't burn hydrocarbons) at the major manufacturers are small to non-existent." At the same time, the global auto industry continues to grow, and Tesla's main competitors aren't from other electric carmakers, but the traditional internal combustion engine.
Musk claims that if you walk into the company's lobby right now all of its patent forms are gone from the walls. "We believe that Tesla, other companies making electric cars, and the world would all benefit from a common, rapidly-evolving technology platform," he writes.
