Tesla Model S EVs now come with lane departure, speed assist AI

When a car's built on such a technology-heavy platform like the one used by Tesla Motors, there are going to be a lot of bells and whistles. More of those little "noisemakers" are being rolled out, as previewed by a new software update. What's most interesting to anyone paying close attention to the slow evolution of the Model S is that the new features are not going to be possible without new components. Tesla Model S sedans will likely need a new camera mounted on the front mirror, but it's not for selfies. Instead, it's there to keep the driver from having too much of a lead foot or straying into another lane thanks to the electric vehicle's software and hardware update that adds Lane Departure Warning and Speed Assist. Other luxury vehicles have long had lane departure warnings, but if you're unfamiliar with the idea, it's when the car emits a vibration through the steering wheel to let the driver know to straighten out if one of the wheels crosses a lane divider. Speed Assist lets the car use a combination of new camera and GPS system to record a particular road's speed limit. At that point, there are a number of signals, including a gray line on the speedometer or an audible chime, to warn the driver that he or she is running the risk of attracting the attention of a Smokey (for you Burt Reynolds fans) and a possible speeding ticket. Tesla has released an official statement that says: Starting recently, some Model S being delivered in North America come equipped with two new features. The features are lane drift detection, which will deliver a warning via vibration in the steering wheel if the driver starts to drift from the lane without signaling, and speed limit display, which will inform the driver of the speed limit and alert them when it is exceeded. These features are necessary to meet the latest standards in the European market, but we have decided to integrate them into Model S delivered worldwide. Whether these features will be an option or included standard is not yet known, but Tesla has said that it is not possible to retrofit the new tech into existing vehicles. The new technology is also vital to make autonomous driving possible.

Is BMW the only real competition to Tesla Motors?

Tesla Motors chief Elon Musk probably isn't losing a ton of sleep over the new plug-in efforts by the makers of the "Ultimate Driving Machine," but maybe he should. That's what the Motley Fool is saying, presenting the case that the California company's real competition will come from BMW. What about the plug-in efforts of General Motors or Ford? Musk can hit the snooze, Motley Fool says. Unlike automakers that are "jamming battery packs into the existing vehicle design," BMW has built its i3 battery-electric and i8 plug-in hybrid supercar from the ground up. Like Tesla, BMW puts its battery packs into the floor of its vehicles. Most importantly, the i3 - and especially the i8 - are real performers. While the i8 is about 40-percent more expensive than the Tesla, it matches the Model S's 0-60 mile per hour acceleration times and handily beats its top speed figures. Tesla sold about 6,900 vehicles during the last three months of 2013 and BMW had more than 10,000 i3 orders on the books by late November and the first year's allotment of i8s is already sold out. The German automaker has what the Fool calls an "outside chance" of selling more plug-in vehicles than Tesla by next year, but Tesla is gearing up its gigafactory to get ready to sell a half-million EVs in 2020, so the race is most certainly on.

Watch the Jaws of Life tear apart a Tesla Model S

As electric vehicles become more prevalent on the roadways, first responders are facing new - and sometimes unknown - challenges when it comes to intense tasks such as the extrication of passengers trapped inside a car. Advanced Extrication, an online training resource for rescue workers, recently posted a video showing how rescuers should respond to vehicles like the Tesla Model S.
The best way to do such a video, of course, is to actually demonstrate the process, so Tesla donated a new Model S just so the Fremont Fire Department could tear it to shreds as the host explains some of the unique dangers specific to electric cars. The unfortunate demo car looks like it just came off the assembly line, meaning it is completely intact to begin with, but we wonder if it would have been more interesting to see how firefighters deal with the car's wiring and DC-DC converter (and other high voltage components) when the vehicle structure has been compromised.
Either way, the entire 37-minute video (posted below) goes in depth showing what rescuers face as they deal with a growing number of EVs. Of course, if all you want to see is the business end of the Jaws of Life going to town on the Model S' subframe, you should skip to the 27-minute mark.
