I'm reading of the quick "fix" to make turn 12 safer. I have no idea how they arrived at this conclusion. The right turn into the chicane is still exactly at the entry point of the paved run off which is NOT adequate!
There are all kinds of scenario that could present a rider falling at the end of turn 12, like a blown tire, front end wash, stuck throttle (god forbid) etc. That short straight between 11 and 12 allows the riders to pick up significant speed!
I'll assume Barcelona is a modern city. There is a better solution! They could right now hire a pulverizer and turn that asphalt into gravel in a matter of an hour. I'm not kidding, I hired a pulverizer almost to the day a year ago. I had 3500sq ft pulverized into gravel of the same type and consistency as track gravel. It's not even expensive, it cost me $2500 to pulverize 3500 Sq ft. And I had it done in an hour!
KROPS, if you're still awake, talk to the safety people. Have them contact a company with this equipment. It can literally be done tonight or in the morning! I have video of this machine in action. It will turn that entire run off into gravel. You can even decide how small or large, how deep or shallow you what the gravel to become. This is an absolute viable solution and far better and SAFER than what they are proposing.
