I asked ChatGPT what the heck these things are called:

Those yellow, bumpy pads at crosswalks are called "truncated domes" or "detectable warning surfaces." They are designed to assist visually impaired individuals by providing tactile feedback, indicating the boundary between the sidewalk and the street.

Shot it with the black E-PL7 the other morning. Didn't shoot anything this morning. Shot so many kite and cedar waxwing shots that I made too much work for myself. Just concentrated on walking briskly this morning.
