Oh....
Hybrid Tractor trailer rigs can haul an extra 40% more weight than an EV tractor trailer rig because of the weight allowance WHILE experiencing 20% fuel savings at the same time.
Drive by wire systems are awesome. Each tire gets a motor and torque. For 18 wheels that's a minimum of 540 Horsepower all wheel drive with just 30 horse motors on each wheel. (They can be stronger than that....40's and 50's are not out of range)
And each wheel is independent of the others if one loses traction or increases traction over the others.
Edison Motors has several prototypes already looking at full production with standardized bolts, lights, and all the rest.
But they are hybrids. And most logistics (trucking freight) companies would kill for 20% fuel cost savings. The increased load weight is just another bonus. Hybrid tractor trailers weigh LESS than EVs. But they still get the extra weight allowances as a full EV truck does.
Ag is seriously looking at these as they tend to run overloaded as it is with field crops like grains. Hopper bottom trailers have a bad tendency to get overloaded by farmers and then have issues getting out of the fields. (Just normal stuff)
Hybrid trucks aren't much different from train engines . Diesel motors that generates electricity that then turns motors.
