Nobody is forcing people to do this, it's motorsport it's dangerous, accidents happen, just because you guys don't want to do why should you have the right to stop others doing it? They know the risks, they will also believe it will never happen to them, the loss of life is tragic, but they wanted to do it, next you'll be trying to ban all motorcycle racing, as it is by the fact more dangerous than cars.
This.
"Motorsport is Dangerous" is printed on every single ticket issued. And on press passes. As a pro photographer working down on the fenceline, I was effectively signing away any liability. Basically, if I got flattened by an escaped car, then it was my fault for being there. Anyone involved trackside i.e. drivers, riders, marshals and media know the risks. But we do it because it's a passion. You can't just expect us to simply turn that passion off.
The TT is more than just a bike race. It's a whole culture and mindset. And a real rich history behind it. I'm not so into bikes, but historically, there were also similar events for cars - the Mille Miglia and the Targa Florio to name but two, dating back to the earliest days of motor racing. They did come to an end in the 1970s, mainly because the cars in the headline classes got far too big and powerful for the roads they raced on. Think Le Mans-type prototypes on UK A and B roads and you kind of get the idea. There's plenty of interesting reading around those road races - think Moss and Jenkinson... If you can get hold of a copy, I highly recommend "From Starting Grid to Checquered Flag" by Paul Frere, which is contemporary to that.
It's less clear cut with bikes as to whether they should be racing on public roads, but simply by their nature, if something goes wrong, serious injury or a fatality is the likely result. It's not just the TT - circuit racing, where you have run offs and techpro barriers and all the other safety features - is equally affected.
I should make it clear that I'm speaking from the perspective of someone who has been personally affected by a motor racing fatality. Not a driver error, but a freak mechanical failure that happened in the worst possible place, resulting in the car being pitched head on into an earth bank. It still hurts to think of it even now.
