Molt Taylor flying car
I was hands-on with this particular example some years ago when it was owned by someone who lived at Spruce Creek. He had just gotten it and I was visiting someone one hangar over, he asked me to come give him a hand putting the wings on.
Very fussy procedure, lots of pins, bolts, struts, cable disconnects, obviously not for the turn-the-key-and-go crowd. The "car" part was scary - it was a very light, egg-shaped cabin with four skinny tires. It looked and felt extremely fragile, to the point where in a collision between it and a bicycle, bet on the bicycle.
Once the wings were on, it was even more scary. The owner wasn't ready to test fly it yet, so I didn't have to hurt his feelings (or threaten my own aviation ego) by declining to go for a flight in it.
Personally, I'd feel more comfortable juggling hand grenades than riding in or flying in this thing - just because something CAN be done doesn't mean it is a good idea . . .
