The experimenters discovered motorists would wait significantly longer before honking their horns at a new luxury car stopped in front of a green traffic light than at an older economy model. The motorists had little patience with the economy-car driver. Nearly all sounded their horns, and the majority of these did so more than once; two simply rammed into the rear bumper. So intimidating was the aura of the prestige automobile, however, that 50 percent of the motorists waited respectfully behind it, never touching their horns until it moved on after fifteen seconds.
