Like to hell with the median, use that space to widen the sidewalks and plant stuff between the sidewalk and the traffic. People might hate walking next to two lanes of traffic somewhat less if there were 4' wide planters between their delicate meat sacks and the two-ton death machines
It's also absolutely wild that this proposal doesn't even touch the sidewalk widths one bit, 6' sidewalks are what you'll get downtown and you'll like it
Noone that says they'd prefer flashing beacons is speaking in good faith
