Good point of view, but I think that the intention of LEGO when created CyberMaster was to make vehicles. From that point of view it is a great bonus to have some tacho counters, since a toy car don't need them very much (but maybe Crusher needs them).

Do you think a tachometer needs to distinguish direction? Why? Going forward or not, a vehicle _moves_ from one place to the other, so the space moved must always be added, never subtracted. How could you otherwise figure _how_much_distance_ you (...) (28 years ago, 12-Nov-98, to lugnet.robotics)
