Most of the time abuse from cars sounds like "GRREYRRERARSRWERE" or something. I'm not an Ewok so I don't understand their language.
Gob****e car drivers are just part of our world like smallpox was a hundred years ago.
How do you get over those feelings of anger after abuse?
The best thing I have found is when you get to where you are going have a look at your bike. It does not matter if it's a cheap bike or a an expensive bike. Just look at it. Go up and play with the cables, have a squeeze of the tires. Pick up the bike and spin that front wheel, do the same with the rear wheel (hear that tick tick tick), and I guarantee within 20 seconds you will feel relaxed.
