Doubtless, if the exhaust nozzle were to eject its contents at a point, say, eight feet from the back of the car or to do so at the side of the car some way from the vehicle itself, the trouble would be avoided, but neither of these arrangements would be feasible even to a limited extent. [Handwritten in left margin: All] Undoubtedly there is a large proportion of people who are easily made sick when travelling at speeds, due to vibration alone, and I fear we cannot legislate for these. I think it would be useful if we could obtain particulars from those who drove in this car (12-LM) as to whether the passengers who complained of being sick, normally suffered in this way in a train or in any other car, after an extended run, say, of 100 miles, seated at the rear of the car. It would appear that one of the most likely conditions to cause passengers seated at the rear of an open touring car to feel the exhaust fumes, is for them to be travelling with the rear screen in position and with the Cape Cart hood down. It does not appear, however, that the Cape Cart hood was down in connection with the complaints with the 10,000 miles test, nor does it appear from the papers whether there was a rear screen, in fact, fitted at all. I think that probably our efforts should be directed towards avoiding in every way possible, any leakages taking place into a car from : (a) Pedal slots, (b) Floorboards, (c) Avoiding engine fumes at the source, that is, by the prevention of leakage on the carburetter needle valves causing the over-flow of petrol. (d) Oil or paraffin being allowed to remain on any hot part of the engine. (e) Lubrication should be as perfect as possible to prevent unpleasant exhaust. [Signature] P.N. [Handwritten] P.N.
