how do i find out if there is buses on newyears day?

Static Electricity. Cars are based on AMPS and Pumps are based on Volts. Cars are Alternating Current while Gas Pumps are Dead Current. The Pumps are Grounded to hold the charge or Voltage. Alternating Current travels and has no saftey hold. When the 2 connect they ARC or Short. This causes Combustion of the Fuel Vapor in the Pump Line and the Gas Tank on the Car. Shutting off the Car breaks its Alternating Current.Thus, no Static Electricity. Herbert West III http://www.wen2k.com/tell.php?id=804... www.west.herb@yahoo.com

Would a drunk driver not automatically be at fault for a traffic accident?

Gasoline vapors are very flammable and don't need much encouragement to ignite. That's why you're not supposed to smoke, but I've seen people do that too.

Emergency Vehicles?

All gasoline vapor needs is one spark to go off. These signs are precautionary. You don't often see smoldering craters where gas stations used to be, but that doesn't change the possibility that it could happen at any time.

was there a cassandra that worked at FYE who was killed in a car crash?

Newer vehicles have a sensor that monitors the engine's pollutions controls. Part of this system is the "Evaporative Emissions" portion of you fuel system. There is a gasket seal on the gas fill cap that keeps fuel vapor contained within the operating system. Vapors are condensed and burned in the engine to control the pollution from the unburned fuel vapors. IF you fill your car with the engine ON the computer senses a leak in this vapor recovery system and usually will set a "Check Engine light" on the dashboard. You will then have to have a technician put the engine scanner on the engine and shut off the light.
