I've never really liked the Barcelona Montmelo track. When it came onto the calendar of F1 in the early 1990s, it seemed like this track was made after the same formula as Estoril, which it didn't top, much less so when Estoril became unique a few years later by introducing its reverse corkscrew.
The Spanish GPs haven't been too interesting to watch in recent years.
Still, as they felt they needed more runoff in the pre-final corner, why haven't they done something like this, which would have preserved the character of the particular section?
