That's not even the worst view. There is a fan's cell phone video that's horrific!!! It was taken off youtube.
WSBK in Moscow, this year was an abomination. The 1st race was run under the new "flag to flag" rules..(Thank you Carmello Espleta and DORNA).. and was horribly dangerous changing conditions. Then the WSS race ended in tragedy...but the red flags didn't come out until the pack made it back to the accident scene!
I really hope they reconsider the rain rules after this. The whole flag to flag thing is to avoid rain delays, but during the SBK race half the track was wet and the other half was dry, so everyone was out on slicks, then 5 laps from the end, the rain finally unloaded and they finally came in for rain tires.....only 10 riders finished!!! It was an absolute crash fest. The rain was so bad by the time the Supersport race came up, that it should have been postponed....but we can't do that because of TV ratings!!!!
With all the advancements in protective gear, air fencing, run off room, gravel traps, etc. the only scenario they haven't been able to diminish is a fallen rider being hit by another rider. All of the recent fatalities on track (professional short circuit level, at any rate) have been this type of incident. Isle of Man and other real roads races are another story all together. They still contend with solid walls like racers before the 70's did.
