That said, no human driver is likely as consistent as such a system could possibly be. But I agree, the 'bugs' that would become evident if such a system were immediately deployed would become cable tv fodder from day one.
For these reasons, I think carpool/HOV lanes should be replaced with automated driving lanes. Start with long distance travel using road trains/grouped motorcades, with human intervention on entrance and exit, and I think this would be a good place to start rather than going straight to automated in-town commutes. It would do much to alleviate public concerns little by little. I want significantly more testing than 190,000 miles by a few cars before I entrust my life to an automated system.
