Sorry to wade in on this.I agree. I have maintained this all along. Berniece is pushing that the solution is flashing lights to indicate potential hazards ahead.
Which just coincidentally happens to be the product sold by the company that apparently told Jonas Vingegaard and the Itzulia organisers all about the dangers of that descent - before the route was even announced - and then approached Benji Naesen to tell them all about how they crunched all the data and the solution to every problem in cycling is to buy their product.
Which Benji then posted as a 'gotcha' to make Twitter get angry at the race organisers because Benji is both a complete populist tool who will ride the wave of whatever will get him likes on his tweets, and somebody who was literally on the payroll of the team whose boss was most disadvantaged by the crashes in the last couple of weeks (and lied about his objectivity too), not realising that his post also implied that Vingegaard must have ignored the advices too.
Benji becoming a voice that people pay attention to regarding cycling is a bit like giving somebody who's good at Madden and only cares about one franchise a job as a Superbowl pundit.
My 2cents worth: There is no single solution. It will be a range of measures. Such as hay bales, warnings on dangerous corners or maybe fines and time penalties at the discretion of the race commissaires when riders ignore the warnings? Of course bike racers go full gas all the time. What regulates rider speed is their legs, skills and courage - and neutral sections.
But this subject has the potential to be a slippery slope. What if mountain descents become neutral?
