Yowsers!
The one of the car going through the crossroads and missing all the cars reminds me of somehting very similar that happened to me in my first car:
Crossroads in the middle of nowhere, me going slightly downhill to it. I can see my light is on red, but I'm still miles away so just back off the gas to slow down. Cars coming from the left are clearly stopped at the lights also. As I get nearer, still slowing, my light goes to green (and changed before I got there) Just as I roll through the junction at maybe 45-50mph all the cars from my left decide to move and I go through the middle of them, all 4 wheels locked and slightly sideways!
My mate in the passenger seat saw the same as I did: My lights were 100% green, and the other cars were stopped waiting, before moving off!
I put it down to a lights malfunction, but it scared us both stupid!
