In todays Daily Star there is a professor in Cardiff Uni who has been studying car horns for their aggrassion levels:
1. Mondeo (dual horn, strong and assertive
2. S2000 (penetrating and and aggressive
3. CLK (dual horn, strong and insistent)
4. Clio (dual horn, very loud and rough)
5. Corsa (very loud and piercing)
Who the hell pays professors/scientist to do these stupid pointless experiments?
