If I recall correctly the jeep and bike from vCoH were both unable to cause suppression and both were incredibly soft targets. If caught in a bad position they could quickly lose most of their health to a lone unit and ever suffer some engine criticals accelerating their death.
The bike was priced with this in mind at 180 (less health than the jeep)the jeep was 220. So 20 more mp you get suppression, genuine damage dealing and a sliver more health (if the hitpoints between the two games are comparable).
Fair point on the path finding that is definitely a negative (like alot of units including the wc51).
Food for thought.
You could chase units and kill them on retreat path in CoH1, in coh2 kubel doesnt do that, only supresses, after SETUP time
