90% killrate might be a little bit of a stretch, but the problem is real, although not for all locations and not for all types of vehicles -- small civilian SUVs and various humvee-like trucks don't have that problem: more agility and speed. Most importantly, however, is the tuning of a CNN aborad autonomous killer drone, those can figure out the military 6x6 target as it is sufficiently large and distinct to be targeted autonomously, but for smaller trucks its still a problem

So the answer for troop transport and some of the logistics shifted onto smaller vehicles, although the tendency have been there the whole war -- the key innovation was the use of small drones for recon, which basically lifted fog of war and increased kill chain speed for inter-unit operation, i.e. infantry calls an artillery strike precisely on target and from the comfort of a pillbox equipped with a large screen to monitor feeds from 5-10 recon drones hovering 24/7 over allied positions
