Autonomous vehicle regulations vary drastically from country to country. As a result, the Autopilot function you'll find on a Tesla will vary depending on the country you're driving in. For example, the version available to Europeans has a considerably reduced capability. It turns out, Europe is not a huge fan of Tesla customers being used as beta testers in the real world. As a result, Tesla has been forced to release a new software update for the Model S and Model X, warning customers that it "introduces changes to some Autopilot features that will affect how they operate on your Model S [or Model X]."

Elecktrek has obtained the email sent out to Tesla's customers detailing the changes. It's a summary of the updates that include a restriction on Auto Lane Change so it can only operate on divided roads, and a delay of one and a half seconds before starting the lane change after it's activated and the indicator is turned on. There's also a new limit on how far the steering wheel can turn when using Autosteer, and Tesla warns it "can affect your car's ability to maneuver curves or stay within its lane, requiring you to take action."

Adding to Tesla user's frustration, "Summon will require that you be within six meters of your car's location to operate." On top of all that, the reminder to hold the steering wheel will now go off after 15 seconds.

While things like the steering wheel reminder shouldn't be a bother, it must be frustrating for Tesla owners not to have some of the features work as promised. People have already been disappointed with the Summon feature, but having to be within six meters of your car's location renders it pretty much pointless outside of edge cases.
