Pace, I drove a 'Plastic Pig' once and hated it. I always thought that the only reason Reliant made them with 3 wheels was because you could drive them on a motorbike licence. A friend has a Bond Bug in his hangar. At speeds above 70, I'm reliably informed that the handling is marginal. Of the millions and millions of cars built over the last 100 years, I'd bet that 99.999999% had four wheels. Probably a good reason for that. Incidentally, the AeroCar is frontwheel drive.
But I take your point that most nosedragger light aircraft are trikes (although - strictly speaking - just every jetliner ever made has two wheels at the front!)
