When I let my workmates drive Merc, the comments were:"Nice, but unstable", it was same with my previous 20" folding-bike. It might make folding bikes more popular if they were more stable - if they were more popular there would be more competition - and improvement in quality and innovations.
I think these are more for the case of the stationary bike, to prevent the steering from rotating. I have no idea what they would do to the riding stability.
I tried riding my Swift again no-hands, and it is definitely marginally stable - I can't unwrap my muesli bar without veering all over the road.
Bigger tyres would help since from a pure geometry consideration, these increase trail by a small amount. This explains why some have reported putting on a large size tyre on the front made a good improvement.
