Another notable thing may be when my friend and I used to play a sort of trust game where you were to depend on their eyes telling if it was safe to speed across a four lane highway on your bike...
ok that reminded me of something i used to do when i was like 10 at the most... right by my house was a freeway that was atleast 8-10 lanes wide (4-5 for each side) you couldn't see (atleast from where i would stand) the traffic from one way... i used to just have fun running across it to see if i could make it across safely... must've run across that thing 1,000 times in my life.
