The operation of a motor vehicle, specifically an upscale sedan, in a questionably aggressive manner through a false sense of security, in the mistaken belief that advanced restraint, steering, braking and/or suspension systems and higher chassis build quality will permit the driver to escape collision or injury.
The term apparently originates from the emphasis on safety in Volvo's ongoing advertising campaign.
"Yo! Did you see that Beemer cut off that ambulance and rip across six lanes to that offramp?"
"Monkey got a bad case of Swedish courage..."
