Really funny - bit worried about the aerodynamics at 90 +

Reminded me of seeing the stinking (vintage) diesel bus with blacked out rear window which transports customers down to Agatha Christies house at Greenway. This is fitted with a not very discrete reversing camera above the rear window.
Made me smile as the bus is an environmental move to stop cars piling down to Greenway which coincidentally has limited parking. I'm not kidding you they weren't particles coming out the exhaust you could almost dot to dot the bonnet of the car having followed it a while.
