How about SF to LA (IIRC using a lot of Hwy 33 to avoid such as 99 and 101) - and about 50 years ago BTW - in 5 hrs ~15 min. Over the lengthier route stealth required, that was ~ 93 mph average.
(not moi; but less'n a cargo plane plucked him off the road - the times were noted door-door) Hmmm ever seen 130ish on a farming area blacktop with no lines, sometimes?
But then, these sprints are Ok too, for getting the flavour of what it might be like to -

Oh yeah it *was* on a Vincent - any extras for 2 wheels and no A/c?
