>Horses were more dangerous than cars, but you're still allowed to ride horses on the road.

They may have been at some point, but that hasn't been the case for some time.

>A total ban on manual driving is just not feasible in a democratic country.

I disagree. Maybe not this generation, but supporting manual driving makes the whole system less stable unless you make a road just for them, which is really expensive.

>You would need just as many robotic cars as you would current taxis.

I don't believe this is the case. I see taxis sitting empty for hours. In that time one taxi could have made several short trips. I'm certain that a computer calculating routes, etc., could manage to get the same work done as is being done now with less resources. That's why we made them, after all.
