NASCAR driver Kurt Busch's ex-girlfriend is in court to obtain a restraining order against him, but he claims that she couldn't possibly be afraid of him because she is an experienced marksman, reports TMZ.

Ex-girlfriend Patricia Driscoll testified in a Dover, Delaware court Tuesday that Busch allegedly choked her inside his motor coach after one of his races in September.

Driscoll described the alleged domestic violence that took place on Sept. 26 during the emotional six-hour protective order hearing in Kent County Family Court: "He sprung up from the bed, grabbed me by the throat with one hand and face with the other, and smashed my face into the wall three times," she said.

She claims Busch is struggling with alcoholism and depression.

Sources tell TMZ Sports that Busch's lawyer Rusty Hardin has submitted a YouTube video entitled "Pocket Commando" that shows Driscoll at a gun range flaunting her marksman skills. His legal team says Driscoll calls herself a "commando mommy" on the video and they argue that Driscoll is a "trained assassin" who does not fear Busch.

On Wednesday, Busch took the stand during day two of the protection order hearing, calling his ex-girlfriend's allegations a "fabrication," reports USA Today.

A family court commissioner heard the testimony on Wednesday to decide on a protection order filed by Driscoll last month but there was no decision. The hearing will resume Jan. 12.

The 2004 Sprint Cup champion's temper on and off the NASCAR track is well documented. In June 2012, NASCAR fined Busch $50,000 and placed him on probation for reckless driving on the pit road and a post-race altercation with Ryan Newman's crew members following the Nationwide Series race at Dover.

When Busch rammed friend and fellow NASCAR driver Matt Kenseth's race car several times after the April 2013 Richmond race, Kenseth excused Busch's behavior, saying, "he probably had one of his Kurt moments."
