just to be precise ( or a smartarse

) the fan was left in the radiator duct on the grid (at Monaco) not in the pit.
but the tire warmer thing, is quite a rookie error, that should not happen,
but hey - nobody is perfect.
But I would agree that HRT is not at F1 standard, and should not be in F1 at the moment.
Not because of the tire blanket, but because of their lack of speed, lack of impovement of the former, insufficient funding and constant driver shuffles.
I´m sure other people could do a more sensible job. Sure F1 is a huge undertaking, but it´s the top of open wheeler racing, and the teams permitted to compete, should reflect that in a way - IMO
I hope they bring the 107% rule back, you should not be allowed to race in F1 just because you bought a ticket/place on the grid, and use your team to wrestle money from well founded pay drivers.
I have nothing against the new teams per se, everybody should get his fair go.
But if you are not good enough, then you are not good enough, and go back to GP2 or whereever, and try to improve.
If you want to play with the big boys, you should be ready.
