Brings to mind a case of recce-with-fast-vehicles down at the company level: British armoured divisions each had a Motor Battalion attached - usually cavalry troops (often some flavor of dragoon) - all of whom were mounted in tracked vehicles. Motor Battalions were divisional troops, mind, and not the same as the motorised units which formed the bulk of the division's infantry.
Each company within the battalion had a Scout Platoon of ten Carriers organized in three three-vehicle section plus an HQ carrier. The crews carried 2-in mortars and PIATs, and they were accustomed to working dismounted.
Now this suggests to me that checking terrain ahead using fast, cheap vehicles, at least if you do have dismount scouts, is a reasonable idea - even in the small-scale engagments that CM tries to model.
I've tried it, and you can get good results, whirling around to the back of a patch of woods without drawing fire, disembarking a scout team to sneak about in the woods, and happening upon AT gun positions that never quite saw you. At least in rolling terrain with fair cover, a Universal Carrier - a small target, with good speed across country - has a reasonable chance of survival, especially because their crews tend to pop smoke and back out of sight.
The only trouble is, even then, it's uncommonly hard to pull that sort of recce work off because the embarked infantry don't cooperate. PIAT and mortar teams are too slow, and split infantry squads that are out of command break left, right, and center, even if you don't want them to get involved in any fighting. Pity that there's no two or three-man "scout team" unit. I'm waiting for the day when crews can abandon and then remount their vehicles!
