Have you actually tested Bao-8 or Bao-5 in these environments? We have really not heard about getting through muddy environment as problems. And I've listened to a lot of this stuffsure agreed. I'm approaching this from a perspective of an off road enthusiast. While the community generally likes the power/torque of EV's and the ability of EV/Hybrids to do vehicle to load charging of camp equipment, right now the heavier weight puts them at a disadvantage which it comes to muddy, sandy, or even gravel terrains. This can be offset with tire selection and some other things but it's still a challenge.
