Yes, there is.

Nope, are you old enough to be out of diapers?

Idiotic nonsense, rush hour traffic is caused by the majority of people
going to and from work and roughly the same time.
Computer controlled cars would have no effect on people's work hours.

Train track converge in a very limited number of places and are controlled
by a physical switch. A train can go many tens of miles in urban areas
without passing a switch and approaching hundreds of miles in rural areas.
Cars on roads will be changing lanes out of necessity every half mile or
so on freeways and every block on surface streets.

It takes a lot more than just a computer to make a computer controlled car.
It also takes a pile of sensors and electro-mechanical actuators that
do not exist in current cars and there is absolutely no standardization
in current cars that would enable adding such devices to current cars.
Each and every car make and model out there is unique.

Childish nonsense.
You are talking about a government mandate that would force the poor
driving decades old vehicles to spend major money that they don't have
on your wet dream.
That is never going to happen in the real world.

What network?
The cars you have been babbling about are autonomous and there is NO
network nor will there ever be such a network covering every dirt road
in the country.

Who get sued when the CPU fails and wipes out a couple of kids?

Potential liability has stopped MANY wet dreams.
