There is no real end to the learning we all have to do is there. I felt I was an expert, or at least competent after 6 months, but realized after 2 years that was not true.
These days I am impressed that I can put the bike away for 4 months and when I get back on it only takes a couple of rides to feel back to where I was. It used to take a lot longer.
Up here I find most people help bikers when they can, but there are always the idiots, maybe they just lost their job, or divorced, or something else is making them miserable and they have no tolerance for bikers. Stay clear of those people when you spot them, pull over, slow down, whatever you need to do to get clear of them.
