Please be careful, because a poorly trained motorcyclist is more dangerous to you than a cager.
Why? Well, I'm going to do a lot of generalizing here...
- They're overly aggressive
- They have yet to fully know their bike
- They may try dangerous things like lane splitting (in "normal" states

- They don't quite know how to share the road.
It's not just a collision with them you have to worry about, but evading the collision or traffic snafu they may cause with others.
Rant over.
