Driving in America is actually really confusing. And no I'm not just saying that because I grew up driving on the left side of the road. No, the reason it is confusing is because a lot of the road-rules aren't actually upheld, but stand more as a "guideline". Take roundabouts as a prime example:
Roundabouts are actually really efficient when you think about it. You don't actually need to stop when you come close to entering. If there are no other cars in sight, you simply move through without any friction.
Compare that to the typical 4-way intersection prevalent throughout the States. For me that is the most confusing thing in the world! It's confusing because no one actually abides by the rules! In Australia if you're at an intersection you should always give way to the left. If there is someone opposite you and you are turning, you give way.
Giving way makes sense.
In America there seems to be this bizarre courtesy system. Some drivers think they're being kind by letting you go first. But actually, this creates chaos, especially when other cars are mixed in as well. Other times there is this unspoken rule where whoever get's to the intersection first get's to go first.
I've had so many awkward stand off's at intersections it's starting to get ridiculous! I'm trying to learn the ways but still can't wrap my head around how it works.
Don't get me started on roundabouts! Some American's I've spoken to have never actually "seen" a roundabout in their life! One rule of thumb when driving through a roundabout in the US: Never assume someone will give way. I have already been multiple near-misses as the driver in the roundabout. Usually other drivers simply just plow straight in without even looking! Other times drivers literally stop in the middle of the roundabout to give you to you! Weird.
Anyway, I'll stop now.
