Autonomous vehicles, which will be predominantly electric, will quickly become adopted in the freight industry because of their running cost savings when they reach full autonomy, and will gradually become acknowledged as safer than vehicles driven by humans alone.
Where there is currently an acute shortage of HGV drivers, autonomous vehicles will solve the problem, although for some years there will also need to be a person in the driving position.
Freight vehicles have to comply with strict weight limitations, so their batteries energy density is more commercially critical than on other electric vehicles. The more energy you can store for a given weight, the more earning cargo weight that can be carried. Additionally, the more energy that can be stored the longer the range of the vehicle.
