Hello, Sorry, but this photo is not a fashion statement of bigger motors, better exhaust headers, etc. Besides, those all contribute to the danger apparent. It is simply stating the open window in the rear sucking in any exhaust fumes, regardless of where the actual tip is pointed. It all come down to the big box vans then and now creating an air flow that sends fumes up/over and around the rear, before they get blown farther back. The old vans and station wagons with rear opening windows were the cause of many folks getting headaches and passing out due to the fumes and silent CO floating around. As a station wagon and van owner from the past, it was a daily happening to all owners. Jnaki Whether it is an old van with pop out windows or windows taken out, a good seal is a must. I f one wanted air flow, the window vans had side opening windows and with the front doors open, created a flow. But, the farther back one goes with open windows, it is getting close to the danger of sucking in the CO and ill feeling. It is a fact of life as the wind flows over cars/vans/trucks. Open windows suck in dangerous fumes. The design of rear exhaust pipes and flat surfaces also applies to powerboats. It is dangerous to sit at the stern transom as the exhaust pipes are right there and the same thing as cars, the exhaust comes out and up into the conversation deck level with the pipes. YRMV Ever wonder why all new station wagons and SUV vehicles don't have rear door window roll downs?
What ever it is … it was never a high production. The commercial air line industry went quickly to jet engines as the piston engine’s maintenance was always high. Jet engines have continued to improve where it’s tough to get the efficiency into the piston propeller any more on an long term basis…the turbo prop is still a viable alternative for short hauls and limited private use.
