G'Day,

The suburbs near the international schools (Minhang, Hongqiao, Qingpu) have a lot of teenagers and adults on scooters, the noisy - non plated- annoying scooters mention in the SD story above.
Go to the Starbucks / Subway / Burrito Shack near the American School (Puxi Campus) and you know what I am on about, just up the road near the CitySupermarket outlet you find some scooter "tuning" shops that caters 99.9% to the laowei kids & parents......

No, I am not a teacher, just a lot of logistics and warehouse companies are located near the American school (Puxi)......
