The simple and sad facts of the matter are that if a full size motobike were unleanable, it would corner like a drunken sailor. Even a pushbike pedalled by an overweight octogenarian nun MUST lean in order to travel in anything but a straight line!
It follows that a small, unleanable model, no matter how exquisite in apearance, cannot handle one whit better than our drunken sailor or corpulent nun, except by addition of a magnet and outriggers to nullify the effect of a very high centre of gravity. And then it looks plain daft going round a bend in an attitude that bears absolutely no resemblance to what we have all seen in real life. The moment you see it doing what your entire lifetime's experience tells you is quite ridiculous, the necessary 'suspension of disbelief' is rendered completely impossible. The lack of lean is no trivial, pernickety detail, it is the absolute destruction of the slightest possibility of acceptance by slot RACERS as something to be raced on a slot track.
So, tremendous and very sincere admiration for Scalextric in producing truly gorgeous models of these immensely attractive machines. But simple, plain, common sense says they will never catch on as desirable slot racing machinery. They are unerringly destined and doomed to a life of shelf queenery, apart perhaps from the occasional demonstration to show that they are actually capable of propelling themselves - if only in a somewhat perverse and unnatural manner. All the upbeat talk that can be brought to bear, and I'm sure there will be plenty of that, can't alter the simple fact that they look plain DAFT going round a curve and any increase in cornering speed endowed byadditional magnet or weight only serves to make them look yet dafter in motion.
Shelf Queen - YES!
Slot Racer - No way José!
