> In a lot of European countries, vehicles entering from the right (aka merging onto the highway) have the right of way Really? In Ontario, entrance merge lanes are marked as if the opposite is true, with "lane ends 300 m" signs and painted lines all the way until it tapers off to nothing. I'm not sure what the law says, but this creates the feeling that "you're lane is ending, not mine", and it's entirely up to entering traffic to match speed and find a gap. Basically, freeway traffic shouldn't adjust their speed unless it's the only way to let entering traffic enter (if there's no room). In contrast, most US states seem to immediately merge the two lanes into one really wide lane that gradually (or rapidly) tapers down to normal width. Often without any warning signs for freeway traffic to expect merging traffic. (Some US states also do this for exit ramps, which creates the dangerous situation where some drivers will accidentally take the exit at freeway speeds. This happened to me once at night, and I had to slam on the brakes before running the stop sign at the end.)
