Seems to me, a better and more universal solution would be for the money to be spent developing self driving cars. The benefits of such a system would be huge.
1) The number of cars (and thus people) that could travel on the same road would probably double or triple, since self driven cars wouldn’t cut each other off, or drive slow while talking on the cell phone.
2) Time spent in the car could become productive. Rather than “driving” you could safely do a whole variety of things.
3) The number of people who die annually on our roads is something like 50k, and the number injured is significantly higher. Self driven cars should have no collisions. The savings from this would be huge. (Not only lives saved, but think of the money not spent on auto insurance, and ambulance chasers)
To me it’s a shame that when the govt talks about stimulus, they don’t have the vision or leadership to propose something like self driven cars. Hey, if we can put a man on the moon, we can design a system of self driven cars.
