I’m absolutely seeing more of them. They’re all relatively new stickers on newer and older cars. They’re all of about the same few designs. They’re actual bumper stickers, not magnets or signs hung with suction cups in a rear windows, so they’re basically permanent. Permanent student driver stickers just don’t make any sense for their supposed purpose. The stickers are going to last so much longer than it would normally take anyone to become a mostly proficient driver.
