In the good old days of British Leyland, my family's dealership took delivery of a new car which the mechanics found a little difficult to drive. Examination revealed that the gearbox had , quite literally, been fitted so there was one gear for forwards and the rest for reverse. Only BL could achieve such a masterpiece ! Goodness knows how they achieved that; it sounds impossible.
And some Lotus cars could do an extraordinary speed in reverse, but I think that was deliberate.
