I was a naysayer...and still think it quite the eyesore (however I originally stated it looked a "proper abortion"...so it must be growing on me). However, F1 is a dangerous endeavor, and it is quite possible in the future that the HALO's presence will prove detrimental. Now, the score is HALO 1 to zero...and think the odds are in favor of it saving more than the converse.
Interestingly enough, I was also quite the Gros detractor. In those few minutes watching live...awaiting news...I became quite ill due to the possible foreboding outcome. I fear watching such a fatal incident live would have permanently soured me. Thus, my hated HALO that saved Gros has allowed me to continue enjoying my favorite sport. Life is indeed strange (and 2020 sucks).
