The regulation regarding electronic items being intrinsically safe, is purely one of reducing risks,and according to the MMCC/COTC and one designed to keep outside agencies happy.

The bike is of course the most significant heat and open spark sources likely to be un the vicinity of the pits, but of course has to be there. Other items do not, and hence are unnecessary risks.

It was repeated to competitors over and over again that banning electronic items was purely in order to satisfy the issuers of the pit lane petroleum licence. If it gets revoked, there is no fuel in pit lane and hence racing (of any consequence) on the island ceases.
