This mom was left stunned when her Tesla sensed a hazard through its Full Self-Driving Mode – before she’d even realized what was going on.
Dana Chandler was riding along in her Tesla, when it started moving off to the side of the road.
This left the Maryland resident confused, as there were no obstructions in front of the vehicle.
But then it quickly became apparent what was going – and she was left in awe.
Tesla’s Full Self-Driving technology continues to spark debate
Self-driving cars are very much a part of our modern roads.
What was once a sci-fi invention is now a reality.
Admittedly, there are plenty of people out there who are still skeptical of the whole idea – only 19 percent of Americans would own or lease one, according to a Gallup poll from earlier this year.
But regardless of personal tastes, nobody can deny that the technology has come on leaps and bounds in a few short years.
There are plenty of videos on the internet which are a testament to this.
There have been several road trips undertaken using Full Self-Driving technology, but it’s also proven itself capable in high-stress situations.
Just look at the scenes on this chaotic Indian street for proof of that.
But despite all the clips out, Full Self-Driving still finds a way to surprise us.
This Tesla owner was left stunned by what her vehicle did
Dana Chandler shared a clip to X, writing ‘Don’t question when your Tesla pulls a quirky move’.
What qualifies as a quirky move?
In the video, the car is shown turning off to the side, leaving her confused.
There are no cars around, so the intention isn’t clear.
Then the noise of an ambulance siren comes into hearing range, and it all comes together for Chandler.
She was left stunned.
Don’t question when your Tesla pulls a quirky move. FSD heard that ambulance siren before I did and got us over. 🚑🔊👍 pic.twitter.com/z4MrHLHUSr

“I totally didn’t hear that whatsoever!” she exclaimed.
“That was weird! I didn’t see that coming!”
Other drivers were impressed by what they’d seen
Plenty of people were taken aback by the technology’s capabilities and shared their admiration – as well as some stories of their own.
“The same happened to me with a firetruck. The CT moved over and I let it happen, then I saw the truck. Inspiring,” one X user wrote.
“My truck did the same thing. I got p***ed at first thinking it was phantom braking,” another said.
“Then I saw the ambulance pulling out from my left with lights on but no siren. The other human drivers kept driving.”
It’s truly remarkable what technology can do in this day and age.
