Love bike racing. Although I am a permanent resident in Doha, I attended only 2 MotoGP races at Losail (during my first 2 years in the country) and stopped going ever since.
While it was nice for a little while to watch the riders doing 300 Km/h down the straight, It is not really exciting to me (and I think I speak on behalf of a lot of other fans) to stand at the start/finish line and practically try to watch the race through the big screens. Viewing areas should be created at various places around the track (as you can find in other venues around the world) so that you can see the live action you came for, or the number of visitors will continually decrease.
