What about a transmission? Does Tesla's semi-truck offer one?  

The Tesla Semi truck is unlike other vehicles in that it does not have a standard transmission.

It has four electric motors instead, two for each wheel. To increase torque at the driving shafts,

these electric motors employ gear reductions, giving

the truck the muscle it needs to pull hefty trailers. Because each motor can regulate its own speed and torque,

the driver can focus on the road without constantly adjusting the transmission  

. This makes driving less complicated and tiring for the driver,  

it will come down to personal tastes and needs, as well as reviews and ratings from experts in the field.
