Everyone is entitled to their opinions. M cert since 1972 with a break starting in 1980 thru 1992. I have 6 documented rides that include big portions of the California interstates. Never had a problem with the CA drivers. Perhaps they gave me space because I was a curiosity. A busa with Givi boxes, full height windscreen and tankbag, more lighting than usual, gps, escort, a hazmat stitch, et al.
There are only 6 states in continental US that I haven't ridden in. I've got mileage throughout the United Kingdom and skipped around in Canada and Mexico.
To me, the toughest locations are the major beltways at peak; try the 495 around wash, dc or the 610 around houston, tx.
nope, no crack here because I drive for a living.... pee in this cup please...
