Life in the USA: The School bus - Wikipedia, the free encyclopedia

"Outside of North America, the yellow school bus is not as common; buses used for the purpose of student transport are typically closer in design to mass-transit buses. These buses may be painted yellow or other similar shades, but school bus yellow is not a government specification like it is on school buses from the United States or Canada and so is generally seen only on buses imported from North America. School buses outside of North America typically do not have traffic priority while loading or unloading students; school bus traffic stop laws differ from North American counterparts (if they exist at all)"

Environmental Benefits - American School Bus Council
"Some 480,000 school buses carry 25 million children— more than half of America’s schoolchildren — each day, making the school bus industry the largest form of mass transit in the United States."

Safety
Standard No. 217 - Bus Emergency Exits and Window Retention and Release September 1, 1973 This established requirements for bus window retention and release to reduce the likelihood of passenger ejection in crashes, and for emergency exits to facilitate passenger exit in emergencies. It also requires that each school bus have an interlock system to prevent the engine starting if an emergency door is locked, and an alarm that sounds if an emergency door is not fully closed while the engine is running.

Standard No. 220 - School Bus Rollover Protection April 1, 1977 This established performance requirements for school bus rollover protection, to reduce deaths and injuries from failure of a school bus body structure to withstand forces encountered in rollover crashes.

Standard No. 221 - School Bus Body Joint Strength April 1, 1977 This established requirements for the strength of the body panel joints in school bus bodies, to reduce deaths and injuries resulting from structural collapse of school bus bodies during crashes.

Standard No. 222 - School Bus Passenger Seating and Crash Protection April 1, 1977 This established occupant protection requirements for school bus passenger seating and restraining barriers, to reduce deaths and injuries from the impact of school bus occupants against structures within the vehicle during crashes and sudden driving maneuvers.

Standard No. 301 - Fuel System Integrity - School Buses April 1, 1977 This specified requirements for the integrity of motor vehicle fuel systems, to reduce the likelihood of fuel spillage and resultant fires during and after crashes.

Food Machine
Over the past century, an American industrial revolution has given rise to the biggest, most productive food machine the world has ever known.

In this episode, host Yul Kwon explores how this machine feeds nearly 300 million Americans every day. He discovers engineering marvels we’ve created by putting nature to work and takes a look at the costs of our insatiable appetite on our health and environment.

For the first time in human history, less than 2% of the population can feed the other 98%. Yul embarks on a trip that begins with a pizza delivery route in New York City then goes across country to California’s Central Valley, where nearly 50% of America’s fruits, nuts and vegetables are grown and skydives into the heartland for an aerial look of our farmlands.

He meets the men and women who keep us fed 365 days a year—everyone from industrial to urban farmers, crop dusting pilots to long distance bee truckers, modern day cowboys to the pizza deliveryman.

Sick of crappy FM radio in your car...move to the digital age!

XM used to be much better before it merged with Sirius. Now they have the same canned crappy DJs on many channels and endless self-promotion adverts. Sigh.

I eventually let my XM subscription run out. I used to get it for almost free back in 2005-2008. I think they charged me $5/month. You could really negotiate with them...and they'd bend.
