If there was such thing as a foul in the racing world this would have to be it.
The Mazda Miata racing club is open to those of all skill levels and can be just as competitive as some of the far more serious racing. The best thing about it is that it is relatively cheap and essentially just racing amongst mates.
These two racers leading the pack engaged in some dirty tactics as they vied for front position. You can see the prankster on the left messing with his side mirror before taking off, impossible to be fixed until the end of the race. Win at all costs I guess!
