I get to visit the circuit at Portimao (Algarve, Portugal) quite often. Many of the few races held there are relatively poorly subscribed. Consequently cars often get strung out quite quickly. Thus racers are not really racing each other and spectators see what are really just demonstration runs. Not much fun for either.
Originally it was hoped that F1 would make use of the track. It does have quite good facilities. As it stands it is, in my opinion, desperately in need of a short cut built in to produce a club circuit. This would, by closing up the cars and bikes, make it more fun for competitors on the on track, give more excitement for spectators and have the added bonus of needing less marshals.
What do you think?
