I don't mind wide and high so much as small and intense. Some of the tiny rear lights are extremely bright and with a very small illuminated area, that's quite uncomfortable with laser-like scattering across the retina of those behind. The same amount of light emitted over a larger, more diffuse area is more tolerable and simultaneously more visible. But I suppose a broad rear light is less aero or something.
That said I stick Moon lights on my kids' helmets at this time of year, because on kids' bikes the possible attachment points for lights are often below the eyeline of drivers or obscured by their saddles from the viewing angle of a car seat. They're not excessively bright but I want to get something up in drivers' faces.
On my bike I use a dynohub with Schmidt Edelux front and rear. I also have 'to be seen' lights integrated with my helmet, but again they're not too intense.
Tis the season for thoughtlessly mounted, megalumens, wide and high beam floodlights angled directly at one's eyeballs.
I get it, the thought process is actually "this is fucking bright, I'll just light up EVERYTHING in front of me to be safe and be seen" rather than "I'm actually creating quite a dangerous situation here by temporarily blinding everyone and everything coming towards me"
