More than a third of the 22 people killed by a tornado that smashed parts of Oklahoma and Missouri over the weekend died in cars, troubling experts who say vehicles are one of the worst places to be during a twister.
"It's like taking a handful of Matchbox cars and rolling them across the kitchen floor," said Sgt. Dan Bracker of the Missouri State Highway Patrol, surveying the damage in and around Seneca, near the Oklahoma line, the hardest hit area. "This is devastating."
Among those killed were three people in Oklahoma who were rushing to reach a relative's house in their car; a woman whose car was blown off a road near Seneca; and four family members — Rick Rountree, his wife, his 13-year-old son, and his mother-in-law — who were in a van on the way to a friend's wedding when a twister packing winds of 170 mph struck the Seneca area on Saturday night.
"They were on the road when the warnings came," said Rountree's brother-in-law, Larry Bilke.

"They can cover more ground than you can in your car, so unless you know you are moving away from the tornado the best thing you can do is find a strong structure," said National Weather Service meteorologist Andy Foster.
Val Castor, one of the many spotters who bring dramatic video of tornadoes to local TV stations in Oklahoma, said the number of people on the road during tornadoes seems to have increased every year since 1996, when the movie "Twister," which depicts meteorologists chasing tornadoes, came out.
He said driving during severe weather is extremely dangerous for the inexperienced because they don't know where a tornado will form or what direction it will go. Heavy traffic or a broken-down vehicle can prevent people from escaping the funnel cloud.
"Vehicles of any size really don't fare that well in a tornado. Vehicles can be thrown and tossed by the wind," said Rick Smith, warning coordination meteorologist with the National Weather Service in Oklahoma.
As with mobile homes, the problem with cars is that they are not anchored to the ground, and the wind can easily get underneath them. Smith said winds of less than 100 mph can flip a car.
