The guy is a legend, even during the old quali format when nothing would happen for half an hour, it was always worth sitting around to hear what MW had to say. As said before, the most boring race was made exciting by his antics. James Allen bores me to tears. A "past it" Murray would always be better that him, even if it to laugh at some of his mistakes. Thats what made MW the best, he always kept it interesting
Thats why the guys are driving those cars, because they dont make mistakes.
The problem with making overtaking easier is, within the first few laps all the faster guys will have made thier way to front in order of who is fastest... Meaning that the rest of the race is depedent on a driver error or unreliability of the car, which in todays cars anyway, is almost bulletproof (unless your in a Red Bull).
Going back to Williams "tusk" front wing, I thought it was great to see something visibly different to what we have been used to, it was a change. Sure it didnt work but it was worth a try. To appreciate F1 you have to go beyond just the racing, and look at the technologies involved, the stuff is mind blowing. If you want to see "bumper to bumper" racing, then watch the WTC/BTCC/DTM etc.
Going back to my original point, F1 is considered the pinnacle of motorsport, and the drivers are classed as the best in the world. I can guarantee that if a driver makes too many mistakes (unless his name is R Schumacher or T Sato) then he would be out of job
