Oh you do me honour by reading far to much into some flippant comments.
What you go on to say is true. I cannot say the Invacar is pretty but it is an invalid carriage, which seems to be an excuse for the British to create all sorts of misshapen objects that look like anything other than a normal car. Make of that what you will but it almost looks like a case of marking out those who obtain releaf from the State as a sort of payback for being disabled. Certainly makes an easy target for rejection on several levels.
The Nobel, and chums, is pleasing to the eye but like Reggie Perrin (TV character aka Walter Mitty) I get the image of a Dolphin going backwards when ever I see one. You have to remember I am not a normal person, physically so a trike with anything from 18 to 22 stones in the driving position is on a test for its performance under unusual load conditions. The Berkeleys failed for instance. The Nobel also, in this one cars case, with Sachs and good speed. The heinkel powered one I had was much more predictable but not as fast till you got to hills which it could climb well. Reliability, couple of own goals here. Like getting at the Sachs points, brakes worse than Schmitts.
Messerschmitt steering, hard not to like for the simplicity. 8 cheap bushes to replace, possibly a couple of kingpins. Job done. Central seating so no weight off centre to upset the geometry that can be adjusted to suit the drivers load. What is not to like other than the concept which is not to everyone's taste to drive?
Suffice it to say I do not share your appreciation of the Nobel steering design I fear. It is over complicated and has poor leverage on the central steering link, which could have been dispensed with by alternate design. Heinkel made such a simple system, its light and its adjustable. If I were making a composite car I think I would be looking at that to go in it unless it were a tandam, in which case it would need to be geared up which might loose the lightness of touch.
Worse I was suggesting after crashing your allegedly ill mannered Nobel, invaliding yourself, you would be forced by our State to drive an Invacar. This will clearly be beyond the pale for our Fulda buddies to contemplate, so do not do it. Mind you the steering on AC is no work of genius, especially with the wheel studs falling of the hub carrier!
No for ugly I still offer the Larmar, which is chain steered, aaargh! Not so much styling by Jetson as Jettisoned.
Peel Trident / Astronut, with Oscar. Got to be hasn't it? Jetsons as well. I can see why you would want one.
Thoughts, hovercraft Trident with wheels as well. Off over the water Jetson style, yet directionally able for road use.
Oh and enjoy the Nobel of course. Nothing they like better than use plus lots of smiles on faces save the guy who is to bad a driver to overtake.
