There is so much that you don't understand here.

First, it seems you have never driven in Japan. Perhaps you've never driven anywhere? You seem to have no idea what it is like as a driver to deal with bikes who ignore all sorts of road laws. (Running stop signs, for one.)

Second, as a driver I have high quality dashcams in all my cars and I have a ton of insurance. I am hyper aware when on the road but if I am unfortunate enough to end up mowing down some idiot on a bike who doesn't stop where they are supposed to I will have documented proof of what happened. The guy on the bike is the one who is going to end up with broken bones, in the hospital, brain injured (yay no helmets), or dead. I'm going to have a bunch of paperwork to deal with. It doesn't take a genius to see who has more at risk in this sort of situation, and it's not the driver.

Third, you brought up examples from other countries that operate very differently to Japan. The one example you quoted most from was (I think) the UK where they had a few miles of carefully chosen roads they were allowing cyclists to ride against the flow of traffic. That is completely different to Japan where it is a free-for-all on all side streets and only the biggest of roads ban bikes from riding the wrong way. I doubt you will be able to understand this difference but I'm pointing it out anyway.

Fourth, dealing with you has reminded me what shitty people a lot of cyclists are. Not the people who ride a mamachari to the store to go shopping but people like you who take themselves way too seriously. I'd never roll coal on anyone (bad for the engine) but you've helped me to understand why there are people who do it to cyclists. Thanks for that.

Last but not least, you don't seem to understand how Japan works. Here's a little story: Before I started driving in Japan drunk driving was almost like a sport here. People would regularly get loaded and then drive themselves home. They'd joke about it at work the next day. You could refuse a breath test and pay a fine with no further consequences. It was insane. One day for reasons I don't remember everything changed. Today you can't drink anything and drive here, and the penalties are very strict for anyone who is stupid enough to break the law.

Right now in Japan the situation with cycling is like it used to be with drunk driving. People flaunt the laws that exist and there isn't a whole lot of enforcement. Crazy shit like letting bikes ride the wrong way on one way side streets is normal. One day, for some reason, that will all change. It will be very sudden as it often is in Japan. The pendulum will swing from the extreme it now sits at all the way to the other extreme.

I don't know when that will happen but I'm sure it will happen at some point. That's the way things go in Japan.
