All I can say is "we'll see". I personally don't believe these challenges will be addressed in 5 years. Perhaps you do (not putting words in your mouth, since you never claimed this), though we agree that no challenge is insurmountable. 50 years is a good marker here. The PCH is tough but it represents but one slice of the challenge; how about hwy 130 to Mt Hamilton? In January? The idea of a car without a steering wheel is far off to me, even in California.

We'll see.
