When I was in school (90s and early 2000s), it would have been considered extremely embarrassing to have your mom drop you off and pick you up every day. I think it was about the time I graduated that things began to shift. When I was in elementary school, the was nowhere for parents to pull up curb-side and get the kids. By the time I finished high school, the elementary school had blocked off half the curb-side into a separate loop for parents to pick up/drop off kids.
Hah, even more so it was embarrassing to have your parents walk you just to the bus stop for me especially after 2nd grade (which was what separated our early and middle elementary school). Roughly same time period of school. We also only had one bus stop for a pretty big multi-hundred apartment complex.
Things do seem to have changed now. Or it's just that I moved. Not sure.
