What sensors does the Model S have? I&#x27;m surprised that Tesla sold a car with enough sensors for semi-autonomous operation without the actual software until now.<p>For those with more knowledge about cars, how does the sensor array in the Model S compare with similar models from companies such as BMW, Audi, Mercedes-Benz? I&#x27;m interested in knowing if it&#x27;s software or the already installed hardware holding back recent luxury cars from similar capabilities.<p>Also, does anyone know anything about the (digital) security features of the Tesla? This announcement from Tesla makes it clear that the actual control of the vehicle can be modified by an over the air software update. With the recent Jeep hack[0] in mind, does any know if something similar is possible on a Tesla, or if there are some safeguards such as signed updates? As one of the most computerized cars on the market, I tend to think that the Tesla cars might also be some of the most (maliciously) hackable cars on the market.<p>[0] <a href="http:&#x2F;&#x2F;www.wired.com&#x2F;2015&#x2F;07&#x2F;hackers-remotely-kill-jeep-highway&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.wired.com&#x2F;2015&#x2F;07&#x2F;hackers-remotely-kill-jeep-high...</a>
