We're talking about cycling caps, not baseball caps. A cycling cap bill's curve would shade the center of the field of view while allowing peripheral vision. True. Just use what works best for you, short of Yehuda Moon style. Our beloved champions aren't strict either, at least after a bad (styrofoam) hair day: https://ekz-crosstour.ch/wp/wp-content/uploads/2017/10/RSP_1321-1024x682.jpg Just like the curved cutoff in the awful OculuStvzo engineering sample doesn't work... There's no equivalence between the shape of the brim and the shape of the cutoff. The cutoff is designed to manage outgoing light, keeping it where it is useful and not shining it where it is not. Not functionally equivalent, of course. You did see the video he linked? There are only two choices with a reversed crescent cutoff: Either aim it low enough that it does not glare directly opposing traffic, or aim it high enough to keep the 90 and 270 degree fields of vision for fast curves. black-tinted rear window; auto-dimming mirrors; manure-spreading trailer. I have an auto-dimming mirror in my new car. It verges on useless as it does not dim anywhere near enough. I'd rather have a manual mirror so that I don't have to reach up and point the damned mirror at the ceiling so that I'm not blinded by the vehicle behind me. My wife's small Honda has a manual tab on the bottom of the mirror. Flick it with your finger and the "guy behind"'s lights are focused on the ceiling :-) Still leaves the side mirrors vulnerable. Okay, so the trailer will need to be wide enough to block the view, but not as wide as to require the mounting of extra side mirrors on the Honda. I'm not sure about side mirrors. I have them on my pickup and my wife's little Honda has them But I don't remember ever having a problem with them. I sometimes have the problem, mostly on freeways. My wife even has that problem sitting in the passenger seat. It occurs mostly when truck drivers (pickups, box trucks, tractor-trailer rigs) have high headlights and insist on using high beams. It's more MFFY behavior. Our current car has electrically adjustable side mirrors. If speed differentials are small enough that the problem persists for more than a few seconds, I point the mirrors downward until the offender is out of range. If they pass quickly, I just shade my side mirror with my hand. It might be the way I have the side mirrors aimed on the pickup. With my head in the normal driving position I can see that rear edge of the cargo box on the inside edge of the mirrors, and the rest is road. My wife possibly re-aims the side mirrors if they bother her. At least I've seen her adjust them when she starts the car. Hey! After the saga about building small wheels and the spokes that didn't tighten, you never did divulge your secrets of how to built small wheels with long spokes :-) -- Cheers, John B. |
