And then there is the fact that I bet half if not more of motoracing is sponsered by tobacco. So they would start losing revenue due to main events such as F1 and Rallying would decide to bypass the UK. And the UK is the centre of motorsport for alot of the series's. So it would also cause job losses etc etc. The roll on effect would be ridiculous.
The costs of motorsport are spiralling and becoming harde and harder for the teams to find big sponsors. Its unfortunate .
