New driver stickers

In anyone's experience so new driver stickers actually help people be nicer to you. I've been driving with a full license for about five days mainly just a 10 minute drive on a heavy traffic course to be from work. There are lots of curves in the road and blind spots and I find myself improving each day with the occasional person making it difficult for me to merge or refusing to let me do so. I feel a bit less nervous and have a new driver sticker on my car and feel that some people have been nicer. Thoughts on whether or not the sticker actually works/ any general tips. Thank you! Wanted to note I am in the US just in case! Ty
