I got one of those surly cornerbars (offbrand) and they're fucking great, would recommend to everyone. Easily the most comfy handlebars I've ever owned.
Also currently trying to piece together the perfect small size at most medium weight bicycle EDC pouch to chuck in my panniers so I can field repair my entire shit and also help other people.
Pretty sure I'll put some bar ends in there just to slap them into random bicycles so people don't core sample themselves. I am the velocipedal crusader, you will be saved from doctors having to extract a tubular 21mm cross section of yourself so they can figure out what the fuck you managed to lose because you didn't think to put 50 eurodollarcents of bar ends on your stuff.
I need to start riding my bike more because my car tyres have sidewall damage. I almost got hit by a car today though, so I need to wear hi-vis and go construction worker chic.
hi-vis isn't inadvisable but I want to point out that the issue most often isn't car drivers literally not being able to visually see you, it's that they either don't look at all or alternatively their brain scans for "cars" and seeing none assumes this means "clear". Some defensive, but confident riding can help with this, albeit you're still admittedly on the short end of the stick
