Wheel power is weak and power consumption (2kW) is a joke
I think best use of wheels are for carrying heavy cargo in high gravity environments. But wheels are not powerful enough to move that heavy cargo. For example my truck that has 8 large block 3x3 wheels (at 100% friction and 100% power) can't produce enough power to move a large cargo container full of ore up to sloped terrain (close to 1 million tones in total).
People are saying about adding thrusters to the truck but this is not a cheap way compared to wheels and also immersion-breaking thing for an efficient use of wheels.
Second thing is that of course wheels use much less power than thrusters but 2KW is a joke. (For comparison: Tesla Model S engine produce 581KW.)
Also I want to thank for your efforts on improving wheels in the last years to make them bug-free and great for use.
