Once the technology is refined, I don't see it as a bad thing to have driver-less vehicles. Even if it eliminates just one driver from a convoy, it would save costs and also with the reduced drag, save fuel. The way I see it is, we are all consumers. Most of us tend to seek out the best prices for our goods, meaning that companies who fork out more for more expensive transport costs (i.e. conventional transport compared to cheaper driver-less) may eventually be priced out. If we want cheaper stuff, we need to embrace cheaper logistical initiatives.
I know what some people will say; "you wouldn't have that opinion if your family were killed by a driver-less lorry". No, I probably wouldn't. But if the technology is anything like my friends car, it more than errs on the side of caution. If approaching a line of parked cars, if there's less than a couple inches of clearance, it will brake for you, whether you want it to or not (you can shut the feature off before you start your journey, though not whilst driving).
