Thats the differance between Le Mans and other types of racing. Its the car that is important, the driver is just that, it matters note a jot where he comes from, the national anthem will be british and it will be a british win.
If he is driving a Brit car and he has the pleasure to win he should enter the heart of all British fans; Lammers, Shelby, Nielsen etc, all have a special place in Le Mans History.
