Loads! Here's one:
Coming back from Carmarthen heading towards Swansea on my SS180 Vespa in 1971.....I was only 17 at the time.
Started overtaking a truck and it was longer than I thought and I started running out of momentum to complete the pass! Then another truck appeared coming the other way heading towards me.
The oncoming truck didn't slow he just kept coming.......and I was passing the truck in my lane literally an inch or two at a time.
My thought was slam on and try and drop behind, but I was a novice and I was worried I'd end up under his wheels. So I kept inching forward on the overtake!
Obviously I made it through, but it was literally inches either side with neither truck giving any ground.
I realised then that there are other road users who won't think twice about killing you.
