For me it's unnecessary, F1 has an amazing safety record over the past 20 years or so. I fail to see how the halo would stop small bits of debris potentially hitting a driver (Massa style), a clear perspex screen would have been better at that. Compare F1 to MotoGP, one is far safer yet they're not talking about putting stabilisers on motorbikes.
Anyway, we can forget the halo sideshow for now. I'm up early, coffee in hand and ready to go racing!
I'm the scumbag outlaw. You're the pillar of justice. Neither of us like looking at ourselves in the mirror. Do we have a deal?
