loads of people have called for the TT to be banned. However they have done all they can realistically do with safety
Marshals have site of every section of the track, areas are heavily padded. There are qualified trauma doctors on site in various positions along with lots of paramedics. There is also dedicated helicopter support. So I would say they take safety a lot more seriously
All of this may be true but people still die every year, everyone taking part knows the risks involved and are prepared to take those risks, the same applies here in my eyes. Plenty of the the top racers don’t think it’s worth the risk and don’t turn up despite being sponsored by Redbull
