Yep. If it moves, is road legal, and can be computerized, it can be
automated to drive itself. Just keep the mobile home moving so that
it never needs to find a parking space. Progress blunders onward.

Just one problem. The road infrastructure that the US built during
the 1930's depression, and again during the cold war, is falling
apart. Roads are designed to last about 25 years and bridges about 50
years. The better built freeways, maybe also 50 years.

? These things change all the time

What things change? The lifetime of roads and freeways?

No, the roads themselves. Not where you live. But when I came back from coleg 237 was one lane in each direction with a stop sign at 1st street. It is now 12 lanes wide and 880 has gone from being 2 to 12 lanes.
When I go back to visit where I went to skool there is a brand new freeway each time where there was nothing before.
When I drive home I don't even recognize the 405 exit lane - it is now on the left not on the right!! I don't remember ever seeing a left-hand exit lane before that; pretty soon they were in NorCal too.
When I moved here in 1972 they were building 280, and recently built 85.

I would agree that nothing has changed in -your- neighborhood.
