I might not be able to change what manufacturers are doing, but I do try.

I write them to let them know about their dangerous LED headlights. I write them to let them know exactly why I will not buy one of their vehicles, even used, because it has a giant touchscreen interface for core controls that is useless when the sun is shining on it.

I treat owners who are making the streets more dangerous for me like shit, and I’ll tell them why if they bother to ask. most will probably just say fuck off and not change their mind, but some might actually think about how their actions affect people.
