Sounds like fun.
I'm currently in the U.S. and I'll tell you that it was certainly a culture shock.
This is such a car centric society that there is little awareness of the basic needs of those on a bicycle.
Personally, I think that a lot of drivers are ignorant of cyclists as opposed to malicious (although there are a handful of those too).
Having said that, some of the riding is simply epic!
The OP is right to have concerns, in my opinion, but is also correct in trying to do something to alleviate those concerns.
They could do worse than read some of the Blogs on CrazyGuyOnABike for inspiration.
