Costs money to rip and replace existing infrastructure. Counties and cities with less income can’t afford to make such drastic changes unless it’s a higher priority than the other 25 things that need funding

For what it’s worth, I wouldn’t be in 3rd gear at 20mph in a modern turbocharged car.

For my car, 20mph is roughly 2500pm in 2nd and 1700rpm in 3rd. I don’t like to live below 2000rpm because I don’t get spooled up that low.

I use the back buttons as alternative shoulder buttons.

My right bumper button broke and I can’t find cheap replacement daughterboards, so bandaid it is. I can’t just solder in a new switch because the leads on the PCB broke. Seems to be a failure common mode for the bumpers if you ever hit the corner or drop it. The way the bumper is designed transfers the full force directly to the PCB instead of to the shell or any actual structural component.
