An assertive driving mode has been added to the automated driver assist feature.
The setting will follow other cars more closely, change lanes more frequently, and perform rolling stops.
Safety groups often discourage such driver behavior.
One motor safety expert said that it could be safer for an automated system to be more assertive, like a human driver, rather than being overly cautious.
The three driving profiles were added in the October update. The driving profiles feature was restored after the update was pulled because of other issues.
David Zipper, a technology writer and visiting fellow at Harvard Kennedy School, posted a picture of the update to his social media accounts.
The assertive mode is described as: "Your Model X will have a smaller follow distance, perform more frequent speed lane changes, will not exit passing lanes and may perform rolling stops."
Some people on social media think the list of behaviours is less safe.
Matthew said that well-designed driverless systems are safer than human drivers because they eliminate human error.
If a more assertive driving style encourages more drivers to take up self-driving systems than a very cautious style, that could be a net gain for safety.
He said that if we want widespread adoption of automation, drivers would expect the vehicle to make decisions that they would make as a human driver.
When one driver has to pull over in a single lane country road or at a four-way intersection, one driver must make the move first, and that's when human drivers come to an impasse. Two very careful automated cars might be waiting for the other to act.
"This is what the manufacturers are trying to learn at the moment," Mr.
If more people use the systems more because they feel like they're more human-like, that's a good thing.

He warned that it depends on howassertive the system is and that it must avoid aggressive driving.
There are situations when automation can't progress because of basic rules, but it's a fine line between assertive and aggressive.
I don't think we're there yet. I don't think the technology is up to date.
Failing to come to a complete halt at a stop line can result in someone failing their driving test. Many drivers simply come to a slow crawl, but it is considered a dangerous technique.
These appear to be part of the average and assertive modes. The description that the car will not exit passing lanes seems to be contrary to regional rules.
The "Full Self-Driving" feature is only available in the US as part of a limited test.
Several states in the US have made it illegal to leave the right-hand lane unless you overtake. The Highway Code in the UK states that motorists should always stay in the left lane unless they are going to overtake.
It's not clear if the rules about staying in the overtaking lanes and rolling stops will be accounted for by the system.
The company does not respond to questions from journalists.
There have been crashes and incidents involving the technology of full self-driving that have been covered by the media.
It is not a self-driving technology, but a driver assistance feature similar to other car-makers' lane assist technology. It is at level two on a scale of automated systems.
The owners of the car must be alert at all times and ready to take over in an instant.
It is a car called theTesla
