I hate these things with a passion.
Where i live right now, when i go for a walk or a run. Kids will fly past me going about 30kph with no warning or no helmets either. There are these 2 girls that ride an electric scooter together and they blow past stop signs. Im very surprised that no one on these things has been killed on them yet. I also live on a busy road because its one of 2 entrances to get into my neighborhood.
