America’s scourge of violent automobile accidents and deaths must be stopped. 35,000 people were killed in the US by assault vehicles last year.
Limousine capacity must be limited to no more than five passengers, and all must be required to have comprehensive background checks done before entering the limo door.
A stretch limousine traveling across a bridge in the San Francisco area caught fire, killing five passengers and injuring four others, police said on Sunday.
The limo was carrying nine female passengers late on Saturday night when the driver saw smoke coming from the back of the vehicle. He pulled over on the San Mateo-Hayward Bridge but the limousine suddenly burst into flames, trapping five passengers inside, California Highway Patrol Officer Amelia Jack told KGO-TV.
Four other passengers and the driver managed to escape.
Real Science 
A totally safe world would be a very boring world. No swimming pools, no diving boards, no trampolines, no jungle gyms, no cars, no baseball, no football, no fattening foods, etc., etc.
Lord have mercy. Presumably no celebratory chemicals were involved.
