Having lived in So Cal for about 15 years befor moving to China lane spit on a regular basis. It was th only way to make it home on the 405 freeway with out havign to spend 3 hours from LA to Huntington beach (surf city)
I did it every day on the way to work and bak.
Its col ther as teh commuter crowd knows the bikes do it. No one spits out the window at you, no one opens a door on you and the actually tend to move over a bit if the see you in the rear views.
Now there are a few idiots no doubt but for the most part it was not to hair raising.
However I did do it at about 80 MPH whlie trafic was crawling and that is just plain stupid on my part. But then I was only hit once in all that time so not too bad.
I now know what a ping pong ball feels like bouncing between cars. OUCH! Good-bye Ninja 1000!
I found a small nimble bike like the FZR I eventually setteld for for commuting was much better thinner and not too fast but fast enough to get me out of trouble...or into it.
Just my 2 cents but if th state of N.J. is going to say its Ok then after a while I think people will realize it and you might be safe eventually.
Cali has been doing it for decades so the mind set is there. I would use total caution of course in a state that just intros it.
Drive by this rule look n6 directions listen in 8 adn you might be alive to tel about it. Its an aquired skill adn I felt scared shitless at first then I startd to relax and noticed that peopele pullinig into other lanes or moving over in a lane made tell tale moves. A look into the rear view a head movements its all eyes in 100 directions type of driving total concentration but its do-able.
And most important even at high speeds I always looked for an out. Where would I go if a guy suddenly changed lanes on me?
Sorry to get so wordy hope this helped.
