This is sad and also true. I wouldn't go out biking either in a busy street unless l really have to. It's very nice how the streets are well divided and bicycles have a lane but it's true that each day more people are looking down at their phone while driving and their cars go on the biking lane. I don't blame you. I would recommend to keep active and not lose the habit of going out on your bike. I'm happy to read you're keeping the bike so I'm guessing that's your plan. Remember that a body in motion tends to stay in motion and a body in rest tends to stay at rest. The less you go out in your bike the less you might want to go out. Find fun alternatives, you could go to a park or something every week to ride. But that's just my opinion, just do whatever makes you happy and feels safe.
