A woman was filmed frantically swerving to avoid fellow drivers after
her accelerator allegedly became stuck down on a US highway.

Lori
Ubelstad barrelled down the interstate highway in Missouri last Sunday
at speeds of up to 190km/h, zigzagging through traffic, weaving through a
construction zone and careening down the motorway's grassy median strip
just to avoid a catastrophic smash.

Ms Ubelstad called 911 to
explain her predicament and soon State Highway Patrol officers were
dispatched to catch up with the runaway 2011 Kia Sorrento and clear
other vehicles from its path.

She said she tried everything to
stop her car — slamming on the brakes, turning off the engine, applying
the emergency brake, shifting out of drive — but none of it worked.

The state troopers captured some of the high-adrenaline incident on their dashboard cameras.

"Every
[steering wheel] correction is more subtle when you are going over 100
mph [160km/h] and for her to drop down in a grass median filled with
holes and come back up was amazing," said Sgt. Sheldon Lyon of the
Missouri State Highway Patrol, adding that she performed that stunt at
least eight times.

After a 35-minute ordeal covering 95km, Ms
Ubelstad was able to stop her car by following the troopers' directions
to lift up the accelerator while applying the brake.

"She put herself in life-and-death situations several times," said Lyon.

"I
feel sorry for her, but she did an outstanding job of controlling that
vehicle in difficult circumstances. She overcame so many obstacles."
