The 5 biggest questions we still have about the Tesla Semi

Tesla finally unveiled its heavy-duty, all-electric Semi truck, and we're impressed.
The big rig is the sum of all of the automaker's work in one massive package, featuring design cues from its other vehicles and even borrowing their parts, like the Model 3 motors that power each of its "super single" wheels. Musk claims the Semi will also offer truckers BAMF acceleration and performance specs, up to 500 miles of range per charge, and a cheaper cost to operate than standard diesel trucks.
