looking at the UK OOB, the current limber costs you 10 points and the Morris 15cwt truck is also 10 points - who would actually buy a limber when there is a truck for the same cost?

Therefore unless a scenario designer picks it for his purposes (and he can edit the speed if he wants in the designer) - nobody sane will be buying them. Same gos for the suggested extra cavalry types, frankly.

I have really never used cavalry bar a few sacrificial scouts on the attack specifically to draw AI machinegun fires, and the only motorcycles I ever really use are non-dismount scouts to nick an objective (or die trying!). The dismounting motorcycles simply charge off into the blue and get themselves massacred when the enemy spots them a mile off, and the tiny little crews have no staying power.
