I totally disagree. Passing and entering freeways on many onramps are both really really painful with 11 second acceleration.
Granted that acceleration is nice. But I drove my Prius for years (still take it to Canada due to the absence of superchargers on the secondary roads to my destinations) and I lived with it just fine. Some of the above sounds like really bad road design more than underpowered cars. And before the Prius, I drove the Civic for fifteen years, and lived with it just fine.
I don't think I'd want to drive on California freeways, no matter what car I was driving. If I had a P100D Model S I'd still be scared to drive on California freeways.
