Hey OP, don't know if you are still following this thread or not.
I'll start by stating that I DO NOT HAVE A PENIS, so what I say is not based on anything penis.
Your post makes me think that you are a new rider. I understand feeling overwhelmed with the traffic, both two wheel and four wheel around here. I get that scooters are scary adversaries on the road; however those scooters are our brethren and we should not stand divided (same goes for bicycles. )
In a perfect world we would be able to afford those 3 seconds of following distance, unfortunately, here in the Bay Area, it isn't a reality. Experience will overcome fear and serve to replace it with faith, in yourself and your machine.
Your comment about a foot down makes me want to bring you out and practice slow speed maneuvers and basic drills so that you can gain the confidence and skills to ride safely in traffic.
I know that we have been discussing doing this and I for one am willing to part with a few hours to give you a hand.
Motorcycling is one of the best things in my life, I would like the opportunity to share this joy if you are receptive.
Let me know.
