Being near them really makes me think that they're worse, not just useless. Even though I know what they are, I still haven't programmed my brain to think "funny green light on the floor = watch out for approaching cyclist" as opposed "oh funny green light on the floor, look at that... = almost step into path of cyclist who just isn't as eye-catching as the funny green light".
Can I see the funny green light? Sure. Does it make me Think Bike? No. (Although I'll probably get there eventually)
