Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

1. If I'm going up a small hill and can make it to the top before the car, then I'll speed up to avoid a nasty situation -- or, conversely, slow down a bit so the car can pass in a safer zone.
2. I'll take that small pothole head on rather than swerving to the middle of the road.
3. I'll stop talking with the person beside me and move over, without having to constantly be turning my head during the conversation to check for cars.
4. If the car stays behind me for a while (which I can check via the mirror) I'll give a thank-you wave before it finally makes the move to pass me.
5. I have been on roads where I will sometimes choose discretion over valor and the shoulder over the side of a road with a truck passing 2 feet beside me.

I find mirrors more useful on country roads. In the city, I would also just assume there is a car behind me.

I figure is they are so close to the edge that you need to get off the road than they're probably coming off the road with you anyway. Situations I know of where people were hit from behind the drivers were either drunk or sleeping and basically plowed right through them - either way the driver was coming off the road.

Anyway, I'm not going to debate this A&S stuff. I don't think mirrors cause any additional danger so the outcome from use can only be even or better in the end.

Do you ride differently when you see a car in the mirror? Do you move over to the right side of your 3 feet? Do you dive in the ditch if you think they aren't swerving for you??

I assume two things when I ride, 1) I'm invisible and 2) there's a car behind me at all times. I've learned to look back before I make moves into the lane and would never trust a glance in a mirror to give me the full view of what's going on behind me (meaning, you have to look back anyway). Nor do I want anything at all blocking my view to the front left, where there are oncoming cars who want to turn left and potentially hit me (a MUCH bigger concern, imo, than cars coming from behind, I can't tell you how many times some taxi or whatever is watching the cars and not me coming toward him, just waiting for the gap that he can turn, forcing me to grab a handful of breaks and almost find jesus)....
It is important for me to see behind for a couple of reasons. One, I don't typically ride in the gutter, but if I see someone behind me that is close to the bike lane, I will move to the right so I a buffer between the car and me. A mirror is great for just a quick glance behind you to see what is coming.

Two, if I am going to make a left turn at a signal, I need to cross over anywhere from one to three lanes of traffic from the bike lane. I can't turn my head far enough to see all of the lanes and even if I could, I would need to take my eyes off of the road ahead of me which I don't like.

So, I will not ride without a mirror period.

Crossing lanes I'd never trust a mirror. I just sit up, slow down, and take my time looking for a chance to cross. If I can't cross, I go to the intersection and become a pedestrian. No hurry man.


Ibikeowa... nice. THAT makes sense to me!

So some guys coming at you.... at what point do you decide he's about to ass-pack you and you dive for the ditch?

It's amazing the arguments I read to justify not having a mirror. I read the same logic on motorcycle forums about helmets. So someone tell me how not having a mirror is safer than having one. Driving, riding, flying are all the same. It's all about situational awareness and integrating your own position and plan with those around you. Hard to do that with a 180 degree view instead of 360. As the fighter pilots say, "Check six." (Six o'clock)

attach a camera to your seatpost pointing backwards. Run video cable to small LCD TV mounted on your handlebars.

For extra points, add an antenna and watch Oprah while pedaling.

Or, just learn to glance backwards while riding straight.

I think Ibikeowa had good reasons TO have one, but the two reasons I can think not to have one... 1) blind spot and 2) a distraction.

In general, the people that I pass with mirrors are far sketchier and far worse at holding a line than those without. I will give them a lot more room when I pass because they are more likely to get spooked and swerve towards me...

Get a Take A Look mirror and mount it on a pair of sunglasses. I have been using this setup for over a year now and would no more ride my bike without it than drive my car without seat belts. I can see what's behind me with a glance in a fraction of a second and never have to lose sight of what's in front of me. Call me a Fred if you want.

When I originally saw that site, it clearly said the display worked with ANT+.
The last time I looked, I couldn't find a mention of it.

Do you trust the rear view mirror in your car when making a lane change?

I have been on roads that you would need to be an owl in order to turn your head far enough to safely see. I have used my mirror to change lanes and am very confident that I can do it safely without turning my head.

This is the mirror that I use and I would not ride without it. In my opinion, best bike mirror on the market.

Why the car comparisons? Tell you what... if you were doing 20 in a 45-55 zone, would you trust your mirrors to change lanes? I wouldn't. You better owl it!

But... in a car where I'm going the same speed of everyone around and have spent x number of minutes with those other cars and understand my surroundings, yeah, I may just trust my mirrors (eventhough I've cut off a guy here and there in a seemingly mundane situation).

Just sit up, to show you are slowing, take a look back, and start figuring out if and when you can cross lanes. I do it every day at this one point of my commute, it's a hard right, then up a hill of 5 lanes (2 each side and a turn lane in the middle) that becomes 6 when my lane splits. I'm pigeoned into the lane after the turn because the bridge I cross first has no room for me. After the little bridge, I sit up, and start looking back and forth waiting for a big enough break of cars doing 45 or so. As soon as it's clear, I cross. OR, when I turn right, if everyone's stuck at the light, I hammer up and over and take the turn lane to go left all by myself (my favourite days). Easy peasy. No mirrors needed, wouldn't do me any good anyhow.

The irbm is convex, so it is very easy to get a quick look at everything behind you with a quick glance down without any head movement. For me, it is a tool to get a quick assessment of my surroundings, not a replacement for turning my head and taking a look. If i want to change lanes and see a bunch of traffic in my mirror, there is no point in turning my head 10 times until it is clear. Once it clears up in the mirror, it's just a quick head turn as a final check. I also like the irbm because it is a solid mount (vs. Messing with glasses/helmet mount) and it's real glass (vs. Plastic).
+1.

Also, the roads I ride also have a more traffic on them than the photo in your example and I still use a mirror.

Your not going to try to talk me out of my helmet too are you?

I propose an experiment. We need some volunteers.

1st group of volunteers rides with a mirror.
2nd group of volunteers rides without a mirror.
Since too much data is a distraction, we have additional groups:

3rd group of vounteers rides without a mirror and with one ear plugged.
4th group of volunteers rides without a mirror and with both ears plugged.
Continuing with the logic:

5th group of volunteers rides without a mirror, both ears plugged, and one eye covered.
6th group of volunteers rides without a mirror, both ears plugged, and both eyes covered.

Report back in 30 days. I'm in the 1st group.

Sorry but that is wrong. The mirror tells you his lane position. Now that is helpful I'd say. I ride in 50 mph traffic on a road with no shoulder every day and I wouldn't consider doing it without a mirror.
