I read that the majority of cyclists being hit by cars, is caused by them riding on sidewalks (crossing the street from a sidewalk) since cars are not expecting that,
or when cyclists are riding towards traffic on the wrong side of the road. That's what a lot of people do becaues they think it's safer, but it's really not because cars are not expecting to see bikes on the left side of the road, so most times they aren't even looking there.

The safest place for you to ride is actually on the side of the road going with traffic. When it's a wide road and cars have plenty of room to pass without endangering you, you can be off to the side. But if the road is too narrow for a car to pass you, the safest thing for you to do is move more into the MIDDLE of the lane, so that they cannot pass you.
And that is a safe place to be, because they can see you there.

The best thing to do is ride like cars do, and use hand signals for turning...

When it comes to narrow roads that are super busy with very FAST moving traffic - I literally just ride on the sidewalk. There's no way I could ride fast enough to keep up with them and I would just piss off the whole line of traffic slowing them down. A few roads around here are just not designed for cyclists to be on.
Or I should say "slower" cyclists LoL.
I think if you were a very fast road racer type person, you could keep up with fast moving traffic no problem, but not me.

And vehicles appreciate when you drive like a vehicle and use the hand signals and let them know what you are doing on the road, that's probably your safest bet, because then traffic knows what you're going to do so they won't hit you, instead of riding on sidewalks or riding against traffic like some people do when they are nervous about riding with traffic.

Oh, and I totally just ordered a handlebar mirror for my new E-bike, it'll be here in a few days. I've never used one in my entire life, but I think it would make me feel 96% more safe, being able to see crazy traffic creep up behind me, that would give me time to swerve out of the way of some reckless driver accidentally swerves into me.

And one thing I do, because I don't trust crazy drivers, is make sure to utilize all the bike trails and shortcuts in town, and also planning my route ahead of time to take roads that aren't as busy as much as possible, but sooner or later I still end up having to go through busy parts of town. And if I come to a really bad intersection, sometimes I just get off and walk and be a pedestrian for a few minutes. Sometimes I'd rather do that rather than risk my life when traffic is absolutely nuts.
We have very rude drivers here. I've been nearly hit many times.

Just the other day this woman was pulled over on the side of the road by a cop. And he was just walking away from her window, and I smiled at him as I rode by and I was about to pass her car, when she suddenly turned her engine on and swerved right into me. I had to swerve into the middle of the road to get away. We came an inch away from hitting eachother. Then the cop turned his sirens on right away and pulled her over again.

This other recent time, I was just riding by a car that was parked on the side of the road, and he was planned on backing out. I slowed down and stopped because I couldn't make eye contact, but I saw that he wasn't moving so I proceeded to go past, and he backed up right into me. Right into me. It was very slow so it didn't harm me, but still. It's times like that where you need a freaking air horn.
When I can't make eye contact with them, there's really no telling if they've seen me or not. But I'm thinking of ordering an air horn for occasions like that.
