Steering clear of road rage

"#$%^&," a taxi driver grumbles as he gestures toward a driver that just cut him off.

It's a scene we're all familiar with, but not always able to translate.

Chugging along in the taxi, there's a high-pitched squeal and passengers suddenly lurch forward, hitting their heads on the seats ahead. Then the string of expletives flies from the driver's mouth. Some of these rants are mild, some just a single rude word, but most would have a puritan mother turning in her grave.
