Rant - Does anyone feel tired of this constant battle between us and the motorists?

As title, whenever I hop on the road, my focus triples and I go into the fight-or-flight mode. Taking lane in a 60 kmph road, checking mirror, checking for opening doors, getting honked at by cars, dealing with shit bike lane, give way to cars even I don't have to etc.. This and every day for the past 12 months, I just had this moment of realisation. Why can't some of us (those without bike infrastructure) commute in peace? Like back in my home country where I have access to a family car, I don't have to think much about going from point A to point B. Just put on the seatbelt and my brain goes autopilot. I never worried about anything. To be clear, I love biking and exploring places. But the frustration from fighting the motorists builds up every day... Sometimes I just wish to get a scooter/motorbike so I don't have to live like this anymore. Rant over
