I was hunting through the "Search" function looking for stuff about Hood-Bag or Hood-Cover, and stumbled across these exchanges.
The critical line that is quoted above is, in my experience, the
while tucking in the rear window, and pulling out the central fold of fabric
as it indeed makes a major difference to how compressed, or how low, the folded-hood will go, and yet it took me a few years to grasp this.
I also hadn't realised that other models suffered from scuffing and interference between the hood frames and the seat edges, which is a problem I created - all by myself - on my S1 when I modified the seats to make them a) a different (more comfortable) shape, b) more reclined, and c) non-adjustable, to optimise the driving position for the taller driver.
(Fortunately, with age I'm getting shorter.)
Anyway, the solution I attempted might tempt others to try the same approach.
The collision between the seat and the hood frames is brief, and marginal, towards the end of the maneuver, and once the mechanism is properly collapsed there is no residual contact.
However, it was quickly going to bugger up the outer edges of both seats, so I decided to make a pair of period-looking chromed "trinkets" of the sort that Lyons would have used to distract buyers from the baked-bean-can construction of so much of the cockpit, and I think the result does not look out of place.
Furthermore, to distract still further from the fact they're actually a botch, I managed to make them truly useful as a means of retaining the seat-belts, which otherwise - on my car- are a real struggle to extract from behind the seats when you get in.
I won't admit to actually making these, and will just claim they were a period accessory that I found on EBay
PS - If anyone is doing any chroming this winter, would they pop these in for me ?
