on foot (not 20km, usually its something like 3-5km AFAIK, 20km is the width of both sides strongpoints + no-mans-land between), or on some fast and agile one-way craft: motorcycles, buggies, e-bikes
the key idea is that you need something which can get you onto the enemy position either before hunter drones take off, or that a drone won't take out the whole complement, hence the uselessness of trucks
going on foot is not really due to the human wave nature of the attacks, but rather its like WW1 stosstruppen - they use whatever cover they can find and a squad of 4 on foot is much easier to go through bushes used as cover or when weather is not suitable for flying
of note here is that trucks were not really used for transport on the tactical level on the frontline, however lately (with drones from destinus) logistics runs in the rear have also become a problem even 100km+ deep - thats where the 90% killrate figure comes from

That is quite interesting but in light of that my original question remains (except shifted 100 km back) what about troop transport? Are the combatants suffering a 90% killrate on all their large vehicles near the front or if not then what is special about logistics runs?
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
Also .. if that were the case russia would not find volunteers anymore, as the large majority of russian soldiers in Ukraine are there by free will, not because they were force drafted.
