According to mainstream economics, jobs are not an externality (although they are during a recession). The total amount of money to go around after an efficiency increasing change, will be greater. With taxation, this means that in theory everyone can be made better off. In practice, the truckers will be worse off, but you could at least arrange taxes so that the percentage of people earning less than X decreased, for all X.
Then the only argument left is that the change is somehow unfair to truckers. But that viewpoint unfairly privileges the status quo.
One thing that is true is that the adjustment period will be hard.
