We have 50 states and that's like 50 countries, but we all drive on the right. I remember when "right on red after stop" came into being. It was adopted one state at a time over a period of years.In the UK the medians are raised even more. I think this is so when it snows the roads cannot be cleared so everyone gets a surprise holiday.
I try to ride in an alert/relaxed state thinking the same thing: that every cager wants to hit me. I just need to be ready to act when one gets the guts to do it.Obviously you were riding to suit the conditions and alert to any hazards which only comes with experience and good skills by you. I am sure we have all had plenty of close calls as you never know what other motorists will do. We don't have to worry about ice over here but recently riding on the highway a car about 50 meters ahead of me swerved abruptly into the next lane to hit a piece of truck tyre that was laying on the road and sent it flying back at me. I did my best to avoid it but it hit my left leg but I managed to stay upright. The car then accelerated away to enjoy reaping havoc. My wife has just bought her first motorbike and I am trying to instill in her that every other road user wants to run her over. Safe riding.
I had an 1100 Moto Guzzi that ran that way too. I think maybe it could make interstate speed in 2nd gear! It sure did not have the top gear roll-on that my XS1100 has and that scared me good one time passing a semi truck on a two lane highway.70mph at 2700rpm on an HD
