Might there be greater use of half-tracks, both for military purpose and civilian use? French engineers were pioneers in the development of the half-track, especially with durable automotive sized vehicles from pre-WW1. In the 1920-s & 30's French half-track powered expeditions had crossed Africa & Asia; along with other demonstrations of use. By 1940, a variety of half-tracks formed a significant part of the French Armee's motive power. Axis History Forum - David Lehman (A nice summary of numbers and types).
Also, the Laffly truck company made several useful 4x4 & 6x6 trucks that had both military and civilian potential. The Laffly company made fire trucks for a few years following the war, before going under. With an unoccupied France, could there have been enough development of the line, where the company continues as both a military and civilian manufacturer, on par with the Jeep & Land Rover families of vehicles?
Short answer is yes. I touched on this briefly in one of my earlier posts. In May 1940 the French already had more armored utility vehicles in use than the Germans. Most of the German HT in 1940 were unarmored artillery tractors, & only one or two companies per motor rifle regient in each PzDiv had armored HT. The French had a variety of HT and full tracked infantry, weapons, and ammo carriers in their armored and armored cavalry divisions.
So yes, as with the US and British armored divisions of 1944 its very likely the French would have armored infantry battalions in the armored divisions well supplied with HT & other armored carriers.
