Self-driving trucks: what's the future for America's 3.5 million truckers?

The race is on to get driverless trucks on the roads, and experts say the impact on professional drivers 'is going to be huge'

Driverless trucks will be safer and cheaper than their human-controlled counterparts, but that doesn't mean America's 3.5 million professional truck drivers are giving up to the machines without a fight.

Across the US, truckers collectively haul more than 10bn tons of freight each year, but it's a tough job - the hours are long and lonely, the pay is low and the lifestyle is sedentary. In many ways it's a job ripe for disruption; robots v truckers.
