Ferrari president Luca di Montezemolo has expressed his concern at the number of street circuits being added to the F1 calendar.
Circuits in Valencia and Singapore have joined traditional street track Monaco on this year’s F1 calendar.
However ahead of the inaugural Singapore race, Di Montezemolo said the lack of overtaking opportunities is not good for the future of the sport.
He stated: ‘I have the impression it will be one of those letdowns where you cannot overtake, like Valencia. Going forward with these circuits heralds a bad future for Formula One.’
The Grand Prix around the streets of Singapore on 28th September will be the first night race in the sport’s history.
