Irrational things that annoy you (and non irrational things too come to think of it)

The last time I saw it advertised it was 'The Vauxhall Lifetime 100,000 mile warranty' which is clear enough surely?

I don't really follow your logic for the last point though, I don't really see how it implies the lifetime of the car is only 100,000 miles, they're two entirely separate components to the warranty.
