150 ft + 150 ft so 300' ... in perfect conditions? Are we straight and level? What conditions are the tyres in? Wet/dry/oil slick. Brakes in good order? Vehicle size? I recall driving a fully laden 7.5T box van for my diabetic brother (diabetic, hence he couldn't drive the van) moving house. I followed along the A40 (Oxfordshire), UK) behind him and then he cut off down to a roundabout on a slip road - my lorry wallowed quite dramatically as I followed suit and came to a shuddering stop behind him. Luckily I had six large tyres. If it had been wet, I would have shunted him into a busy roundabout. I would have tried to hit a barrier instead but who knows? As someone else said: "2 second rule". When you are my age you can even see it!
