Back in the 60s, a short while after I bought my first Moulton, I had to drive loads of Austin Healey 3000s back and forth between BMC Special Tuning's plant at Abingdon and my employers at Pressed Steel Fisher in Oxford. We were trying to get them to pass
the 1965 US Vehicle Safety Regulations, but it was impossible, because of the shape and engineering of the car, without redesigning it entirely. Which is why BMC pulled the Healeys out of the US market at that time.
A Moulton WON'T fit in the trunk of a Healey 3000, believe me, I've tried it. 🙂
