I reckon "tailgating" causes most accidents on motorways!-I am surprised there are not more fires, a petrol tank is a bomb! Was it the American Ford Edsil [not sure of the spelling] that caused a lot of fires?
What sort of "beans?" Albervin?The ignition temp of petrol is nearly 100ºC lower than ethanol. The air fuel ratio (stoichiometric ratio) for ethanol is twice that of petrol. In a crash of such destruction that occurred in the UK last week those facts really don't amount to a bucket of beans.
