I also encourage people that can (terms and conditions unfortunately apply) to use the solution I have seen around the beachtowns I grew up in with back country 30mph (that means 45mph) roads near the beach with zero shoulder and lots of vegetation and visual clutter that obscure corners, I call the solution the Karen Solution.

Just walk in the middle of the road, slowly and confidently, never ever be in a rush while on these walks, you need to do it nearly every day relentlessly at focused times of day like the morning and have a whole posse that does it too (not together as an event, you need to space your Karens out on patrol) so that everybody is forced to expect there to be old white ladies walking in the middle of a winding 45mph road. At any moment you must be prepared to rapid draw a mildly judgemental scowl/stare at anybody who drives too fast by or if necessary your phone which you can use to pretend to be talking to someone important about the drivers behavior with.

In order to do this strategy you must be wealthy and white or wealthy enough to function as white in your community, but if you are this is a decisive blow you can make towards road infrastructure inherently hostile to pedestrians. You also might get hit by a car, so you know, be ready to be a martyr.
