Wilson, whose own car was clipped in the three-vehicle accident, also involving a Ferrari, pulled a 50-year-old woman from the wreckage of her BMW, according to The Hollywood Reporter.
"He was the hero, he led the charge," said tattoo artiste Sean Heirigs, who was the eyewitness.
Heirigs said Wilson feared the smoke coming from the woman's car could result in flames and decided to save her.
"We were able to get her leg out from being stuck and then she came out and Luke was pulling her through the back trunk area and then we both carried her to the curb.
"And this was all going on while the Ferrari's wheels are still spinning and blowing rubber and smoke everywhere and it's loud and you're smelling lots of smoke and there's glass," he added.
Neither Wilson nor Heirigs was hurt. The woman from the BMW is hospitalised with serious injuries.
