Not true alternatives and I don’t think this is that shortsighted for big truck manufacturers as the issue here is battery capacity and recharge time which won’t be addressed by building more EV trucks using current tech. All the components needed already exist outside of the batteries and once that tech develops further it should be relatively trivial to build these drivetrains. These companies are still building EV cars, which gives them the R&D needed for trucks too since they all use the same components just with different ratings.
