An autonomous tractor-trailer recently completed a cross-country trip carrying a load of butter.
Although autonomous truck and car technology is not yet for prime time, the tests continue.
The impact on the trucking industry will be significant. Personal costs are one-third of the marginal cost of running a truck, even more than the cost of fuel. Eliminate the driver? Costs go down and the potential for profit increases.
Look for more and more autonomous trucks on the road (especially on the interstate highway system), and an increase in the use of truck platoons.
